This should be the last PR to get the `/ci` and `/rebase` commands working in
GitHub Actions. The issue is that our membership settings for `forem/forem` have
everyone set to 'CONTRIBUTOR' instead of 'MEMBER' or 'OWNER'.
Adding github.event.comment.author_association == 'CONTRIBUTOR' should fix this
issue.
I also cleaned up all action files to make the main name of the workflow as
succinct as possible to better organize the left menut of the GitHub Actions
page.
This PR won't fix the issues with the "Run forem/build-containers pipeline"
job in buildkite.yml but I will address those issues in another PR.
* Update to Ruby 2.7.2
* Update remaining files
* Remove VERBOSE from development.rb and test.rb
* Update Ruby version for dependabot and docs
* Readd accidentally removed code
