Upgrade tinymce (#18107)

* Upgrade tinymce

* Omit 'skin_url' instead of setting it to false

The option expect a string value. Instead of setting it to 'false' we
can just completly omit it.
Otherwise we get the following warning:
> Invalid value passed for the skin_url option. The value must be a string.

Although not explicitly mentioned in the migration doc, the stricter check / warning has
probably been introduced with v6.

* Disable pasting of images

From
https://www.tiny.cloud/docs/tinymce/6/migration-from-5x/#plugins-paste:

> A paste default has changed. The paste_data_images option now defaults to true.
> When paste was a plugin, this option was, by default, set to false, which prevented images being pasted from the local machine

* Update toolbar option names
