Fix upload of sample app apk (#1920)

Summary:
This was an expected failure, you can see here how the last step of the "Publish Android" workflow currently fails: https://github.com/facebook/flipper/runs/1873750507?check_suite_focus=true

This is because it no longer runs in a tagging context. We're now providing the tag as an input and my custom action knows how to attach to existing tags by name.
