Comment:

 After the GitHub Actions workflows landed in `trunk`, the plan was to let
 them sit for a bit before backporting to older branches. I think we're
 just about there after the test reporter and Slack messages are set up
 (see #50401 for that).

 I think we can remove this from `trunk` for now, and then I'll return here
 to backport after the Actions workflows are backported.
