Samuel Attard 9928c7d828 chore: harden GitHub Actions against script injection patterns (#50512)
* fix: harden GitHub Actions against script injection vulnerabilities

Replace direct ${{ }} expression interpolation in run: blocks with
environment variables to prevent script injection attacks. Changes:

- archaeologist-dig.yml: move clone_url, head.sha, base.ref to env vars
- non-maintainer-dependency-change.yml: move user.login to env var
- issue-unlabeled.yml: move toJSON(labels) to env var
- issue-labeled.yml: move issue.number to env var
- pipeline-electron-lint.yml: validate chromium_revision format
- cipd-install/action.yml: move all inputs to env vars and quote them
- set-chromium-cookie/action.yml: reference secrets via $ENV_VAR
- Add security comments to all 5 pull_request_target workflows

* fix: allow version strings in chromium_revision validation

The previous regex `^[a-f0-9]+$` only matched git SHAs but
chromium_revision is a version string like `148.0.7741.0`.
Broaden to `^[a-zA-Z0-9._-]+$` which still blocks shell
metacharacters.
