- add `script/test-render-translation.js` to render all translated content to catch malformed liquid that would cause render errors
- improve test output for `script/fix-translation-errors.js` and `tests/content/lint-files.js`
- make it so `script/reset-translated-file.js` can handle files that have been renamed
* create script to fix easy-to-fix frontmatter errors in translation
* improve reset-translated-file.js: allow reverting to the same file from `main` branch
* fix release-notes as well
* also lints liquid in frontmatter
### Why:
A lot of content gets mistranslated, some common patterns are: frontmatter date and enums getting translated, liquid tags get translated or go missing during the translation process. These translation errors are tough to catch, especially when they often come in huge PRs.
### What's being changed:
- Frontmatter is also getting linted against schema as part of `lint-files`
- When an environment variable `TEST_TRANSLATION` is passed,
- `lint-files` will run its tests against all files that have been newly translated (by git-diffing between `translations` branch and `main` branch), and
- results are outputted using a custom jest reporter. The output is formatted in a way that makes it easy to exclude the problematic translated files from being merged, and to share the errors with [localization support](https://github.com/github/localization-support/issues/489).
- Run the implemented translation test as part of the existing `Node.js Tests - Translations` workflow
