Summary:
Just doing some cleanup of the `.github/workflows` folder:
* apply-version-label-issue.yml hasn't been working since 0.72
* ios-tests is unnecessary as it's now covered by test-all
* nightlies-feedback.yml was experimental and last execution was ~5 months ago.
We can still recover them from the Git history if necessary.
