     * For special-purpose jobs where the runner version doesn't really matter,
       prefer `-latest` tags so we don't need to manually bump the versions. An
       example of a special-purpose workflow is `labeler_pr.yml`.
-    * For our testing job `test.yml`, prefer to use the latest stable (i.e.
-      non-beta) version explicitly. Avoid using the `-latest` tags here as it
-      makes it difficult to determine from an unrelated PR if a failure is due
-      to the PR itself or due to GitHub bumping the `-latest` tag without our
-      knowledge. There's also a high risk that automatically bumping the CI
-      versions will fail due to manual work being required from experience.
