Add a workflow_dispatch-triggered GitHub Action that automates the
Monaco Editor update process documented in FilePreviewCommon.md:
- Downloads latest (or specified) Monaco version from npm
- Replaces monacoSRC/min/ with the new version
- Uses Puppeteer to run generateLanguagesJson.html and regenerate
monaco_languages.json (identical code path to manual process)
- Runs ~60 validation assertions across 7 test groups
- Creates a PR with the changes via peter-evans/create-pull-request
Files added:
- .github/workflows/update-monaco-editor.yml
- .github/scripts/update-monaco-editor.ps1
- .github/scripts/generate-monaco-languages.js
- .github/scripts/tests/validate-monaco-update.tests.ps1
