Bump v17.4.5

fix: crash in safeStorage on Linux (#34261 )
* fix: fix a crash in `safeStorage` on Linux (#33913) On Linux, `isEncryptionAvailable()` was crashing instead of returning a boolean before the 'ready' event was emitted by the app. The reason of the crash is that [`CreateKeyStorage()`](https://source.chromium.org/chromium/chromium/src/+/main:components/os_crypt/os_crypt_linux.cc;l=74;drc=35be6215ec8f09e50176f36753c68f26c63d1885;bpv=1;bpt=0) expects the config to be set but the function responsible for setting the config, [`SetConfig()`](https://source.chromium.org/chromium/chromium/src/+/main:components/os_crypt/os_crypt_linux.cc;l=237;drc=35be6215ec8f09e50176f36753c68f26c63d1885;bpv=1;bpt=0), is called only after the app is ready inside [`PostCreateMainMessageLoop()`](https://github.com/electron/electron/blob/main/shell/browser/electron_browser_main_parts.cc#L499). So this changes `IsEncryptionAvailable()` to return `false` when the app is not ready on Linux and uses that instead of the raw API in other places like `EncryptString()` and `DecryptString()`.

+
+Process: [Renderer](../glossary.md#renderer-process)<br />
+_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
+
+The `BrowserWindowProxy` object is returned from `window.open` and provides
+limited functionality with the child window.
+
+### Instance Methods
+
+The `BrowserWindowProxy` object has the following instance methods:
+
+#### `win.blur()`
+
+Removes focus from the child window.
+
+#### `win.close()`
+
+Forcefully closes the child window without calling its unload event.
+
+#### `win.eval(code)`
+
+* `code` string
+
+Evaluates the code in the child window.
+
+#### `win.focus()`
+
+Focuses the child window (brings the window to front).
+
+#### `win.print()`
+
+Invokes the print dialog on the child window.
+
+#### `win.postMessage(message, targetOrigin)`
+
+* `message` any
+* `targetOrigin` string
+
+Sends a message to the child window with the specified origin or `*` for no
+origin preference.
+
+In addition to these methods, the child window implements `window.opener` object
+with no properties and a single method.
+
+### Instance Properties
+
+The `BrowserWindowProxy` object has the following instance properties:
+
+#### `win.closed`
+
+A `boolean` that is set to true after the child window gets closed.

-about the V8 memory cage](https://www.electronjs.org/blog/v8-memory-cage) for

-### API Changed: `webContents.printToPDF()`
-
-`webContents.printToPDF()` has been modified to conform to [`Page.printToPDF`](https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-printToPDF) in the Chrome DevTools Protocol. This has been changes in order to
-address changes upstream that made our previous implementation untenable and rife with bugs.

-  })
-}).catch(error => {
-  console.log(`Failed to write PDF to ${pdfPath}: `, error)
-})
-```
-
-### Default Changed: renderers without `nodeIntegration: true` are sandboxed by default
-
-Previously, renderers that specified a preload script defaulted to being
-unsandboxed. This meant that by default, preload scripts had access to Node.js.
-In Electron 20, this default has changed. Beginning in Electron 20, renderers
-will be sandboxed by default, unless `nodeIntegration: true` or `sandbox: false`
-is specified.
-
-If your preload scripts do not depend on Node, no action is needed. If your
-preload scripts _do_ depend on Node, either refactor them to remove Node usage
-from the renderer, or explicitly specify `sandbox: false` for the relevant
-renderers.
-
-### Removed: `skipTaskbar` on Linux
-
-On X11, `skipTaskbar` sends a `_NET_WM_STATE_SKIP_TASKBAR` message to the X11
-window manager. There is not a direct equivalent for Wayland, and the known
-workarounds have unacceptable tradeoffs (e.g. Window.is_skip_taskbar in GNOME
-requires unsafe mode), so Electron is unable to support this feature on Linux.
-
-### API Changed: `session.setDevicePermissionHandler(handler)`
-
-The handler invoked when `session.setDevicePermissionHandler(handler)` is used
-has a change to its arguments.  This handler no longer is passed a frame
-`[WebFrameMain](api/web-frame-main.md)`, but instead is passed the `origin`, which
-is the origin that is checking for device permission.

 Electron has a fully-fledged governance system that oversees activity in Electron and whose working groups are responsible for areas like APIs, releases, and upgrades to Electron's dependencies including Chromium and Node.js. Depending on how frequently and to what end you want to contribute, you may want to consider joining a working group.

-> Note that this will increase the size of the build significantly, taking up around 50G of disk space

-Write the following file to `electron/.git/info/exclude/debug.gn`
-
-```gn
-import("//electron/build/args/testing.gn")
-is_debug = true
-symbol_level = 2
-forbid_non_component_debug_builds = false

-title: ASAR Archives
-description: What is ASAR archive and how does it affect the application.
-slug: asar-archives
-hide_title: false
---
-
-After creating an [application distribution](application-distribution.md), the
-app's source code are usually bundled into an [ASAR
-archive](https://github.com/electron/asar), which is a simple extensive archive
-format designed for Electron apps. By bundling the app we can mitigate issues
-around long path names on Windows, speed up `require` and conceal your source
-code from cursory inspection.
-
-The bundled app runs in a virtual file system and most APIs would just work
-normally, but for some cases you might want to work on ASAR archives explicitly
-due to a few caveats.
-
-## Using ASAR Archives
-
-In Electron there are two sets of APIs: Node APIs provided by Node.js and Web
-APIs provided by Chromium. Both APIs support reading files from ASAR archives.
-
-### Node API
-
-With special patches in Electron, Node APIs like `fs.readFile` and `require`
-treat ASAR archives as virtual directories, and the files in it as normal
-files in the filesystem.
-
-For example, suppose we have an `example.asar` archive under `/path/to`:
-
-```sh
-$ asar list /path/to/example.asar
-/app.js
-/file.txt
-/dir/module.js
-/static/index.html
-/static/main.css
-/static/jquery.min.js
-```
-
-Read a file in the ASAR archive:
-
-```javascript
-const fs = require('fs')
-fs.readFileSync('/path/to/example.asar/file.txt')
-```
-
-List all files under the root of the archive:
-
-```javascript
-const fs = require('fs')
-fs.readdirSync('/path/to/example.asar')
-```
-
-Use a module from the archive:
-
-```javascript
-require('./path/to/example.asar/dir/module.js')
-```
-
-You can also display a web page in an ASAR archive with `BrowserWindow`:
-
-```javascript
-const { BrowserWindow } = require('electron')
-const win = new BrowserWindow()
-
-win.loadURL('file:///path/to/example.asar/static/index.html')
-```
-
-### Web API
-
-In a web page, files in an archive can be requested with the `file:` protocol.
-Like the Node API, ASAR archives are treated as directories.
-
-For example, to get a file with `$.get`:
-
-```html
-<script>
-let $ = require('./jquery.min.js')
-$.get('file:///path/to/example.asar/file.txt', (data) => {
-  console.log(data)
-})
-</script>
-```
-
-### Treating an ASAR archive as a Normal File
-
-For some cases like verifying the ASAR archive's checksum, we need to read the
-content of an ASAR archive as a file. For this purpose you can use the built-in
-`original-fs` module which provides original `fs` APIs without `asar` support:
-
-```javascript
-const originalFs = require('original-fs')
-originalFs.readFileSync('/path/to/example.asar')
-```
-
-You can also set `process.noAsar` to `true` to disable the support for `asar` in
-the `fs` module:
-
-```javascript
-const fs = require('fs')
-process.noAsar = true
-fs.readFileSync('/path/to/example.asar')
-```
-
-## Limitations of the Node API
-
-Even though we tried hard to make ASAR archives in the Node API work like
-directories as much as possible, there are still limitations due to the
-low-level nature of the Node API.
-
-### Archives Are Read-only
-
-The archives can not be modified so all Node APIs that can modify files will not
-work with ASAR archives.
-
-### Working Directory Can Not Be Set to Directories in Archive
-
-Though ASAR archives are treated as directories, there are no actual
-directories in the filesystem, so you can never set the working directory to
-directories in ASAR archives. Passing them as the `cwd` option of some APIs
-will also cause errors.
-
-### Extra Unpacking on Some APIs
-
-Most `fs` APIs can read a file or get a file's information from ASAR archives
-without unpacking, but for some APIs that rely on passing the real file path to
-underlying system calls, Electron will extract the needed file into a
-temporary file and pass the path of the temporary file to the APIs to make them
-work. This adds a little overhead for those APIs.
-
-APIs that requires extra unpacking are:
-
-* `child_process.execFile`
-* `child_process.execFileSync`
-* `fs.open`
-* `fs.openSync`
-* `process.dlopen` - Used by `require` on native modules
-
-### Fake Stat Information of `fs.stat`
-
-The `Stats` object returned by `fs.stat` and its friends on files in `asar`
-archives is generated by guessing, because those files do not exist on the
-filesystem. So you should not trust the `Stats` object except for getting file
-size and checking file type.
-
-### Executing Binaries Inside ASAR archive
-
-There are Node APIs that can execute binaries like `child_process.exec`,
-`child_process.spawn` and `child_process.execFile`, but only `execFile` is
-supported to execute binaries inside ASAR archive.
-
-This is because `exec` and `spawn` accept `command` instead of `file` as input,
-and `command`s are executed under shell. There is no reliable way to determine
-whether a command uses a file in asar archive, and even if we do, we can not be
-sure whether we can replace the path in command without side effects.
-
-## Adding Unpacked Files to ASAR archives
-
-As stated above, some Node APIs will unpack the file to the filesystem when
-called. Apart from the performance issues, various anti-virus scanners might
-be triggered by this behavior.
-
-As a workaround, you can leave various files unpacked using the `--unpack` option.
-In the following example, shared libraries of native Node.js modules will not be
-packed:
-
-```sh
-$ asar pack app app.asar --unpack *.node
-```
-
-After running the command, you will notice that a folder named `app.asar.unpacked`
-was created together with the `app.asar` file. It contains the unpacked files
-and should be shipped together with the `app.asar` archive.

-slug: asar-integrity
-hide_title: false
---
-
-## Platform Support
-
-Currently ASAR integrity checking is only supported on macOS.
-
-## Requirements
-
-### Electron Forge / Electron Packager
-
-If you are using `>= electron-packager@15.4.0` or `>= @electron-forge/core@6.0.0-beta.61` then all these requirements are met for you automatically and you can skip to [Toggling the Fuse](#toggling-the-fuse).
-
-### Other build systems
-
-In order to enable ASAR integrity checking you need to ensure that your `app.asar` file was generated by a version of the `asar` npm package that supports asar integrity.  Support was introduced in version `3.1.0`.
-
-Your must then populate a valid `ElectronAsarIntegrity` dictionary block in your packaged apps `Info.plist`.  An example is included below.
-
-```plist
-<key>ElectronAsarIntegrity</key>
-<dict>
-  <key>Resources/app.asar</key>
-  <dict>
-    <key>algorithm</key>
-    <string>SHA256</string>
-    <key>hash</key>
-    <string>9d1f61ea03c4bb62b4416387a521101b81151da0cfbe18c9f8c8b818c5cebfac</string>
-  </dict>
-</dict>
-```
-
-Valid `algorithm` values are currently `SHA256` only.  The `hash` is a hash of the ASAR header using the given algorithm.  The `asar` package exposes a `getRawHeader` method whose result can then be hashed to generate this value.
-
-## Toggling the Fuse
-
-ASAR integrity checking is currently disabled by default and can be enabled by toggling a fuse. See [Electron Fuses](fuses.md) for more information on what Electron Fuses are and how they work.  When enabling this fuse you typically also want to enable the `onlyLoadAppFromAsar` fuse otherwise the validity checking can be bypassed via the Electron app code search path.
-
-```js
-require('@electron/fuses').flipFuses(
-  // E.g. /a/b/Foo.app
-  pathToPackagedApp,
-  {
-    version: FuseVersion.V1,
-    [FuseV1Options.EnableEmbeddedAsarIntegrityValidation]: true,
-    [FuseV1Options.OnlyLoadAppFromAsar]: true
-  }
