ci: Re-run PR tests when leaving draft mode (#4594)

Because our release PRs are created with the default GitHub token, they
do not trigger test runs. This is a feature of GitHub that prevents
recursive loops of workflows.

This change makes it so that marking a PR "ready for review" will
trigger the tests to run again. This gives us an easy way to trigger
test runs on a release PR, by marking it a draft, then marking it
"ready" again.
