Cleanup the .github/workflows folder

[cortinico]

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.

Changelog:

[INTERNAL] - Cleanup the .github/workflows folder

Test Plan:

Will wait for CI result
