Tests

1. Merge this PR
2. The site should deploy on GitHub Pages.
3. Note: action-gh-pages warns that the first deployment with the github.token may fail. I didn't observe that in the test repo, but it may happen.

I branched off of marco-addNewHelpSite to create this PR. Once #9519 is merged and I merge main into this branch, the diff and number of commits will look a lot more reasonable.

This is ready for review but I'd prefer to wait until I'm not OOO to merge/live-test

Awesome, big fan of using dart-sass, and thanks for addressing all these changes that will enable us to use it for the help site @roryabraham!

[roryabraham]

Let's test this out!

@roryabraham looks like this was merged without passing tests. Please add a note explaining why this was done and remove the Emergency label if this is not an emergency.

[roryabraham]

This was passing tests.

One thing I'm noticing is that HelpDot PRs have the potential to trigger unnecessary NewDot PRs. It won't happen now because the checklist is locked, but it's something we should clean up in a follow-up

HelpDot deploy running here: https://github.com/Expensify/App/runs/7204996726?check_suite_focus=true

Weird, the community action didn't work with the ref we used in this PR:

I had only previously tested it with a tag, which goes against our GitHub Actions security guidelines for this repo.

Another thing I'm noticing is that there's no slack alert if this workflow fails.

✋ This PR was not deployed to staging yet because QA is ongoing. It will be automatically deployed to staging after the next production release.

Ruby cache worked so the second deploy was super-duper quick 🎉
