Fail on tag mismatch

[KevinBatdorf]

Is your enhancement related to a problem? Please describe.

If you mistakenly forget to update the stable tag, the deploy will happen but .org won't pick up the new version. This is never expected.

Describe the solution you'd like

The workflow should fail if the tag doesn't match the stable tag

Describe alternatives you've considered

I could probably write something in the workflow before this action runs but it feels like something the action should handle since there's never a case you would want to push the tag with a mismatched stable tag.

Additional context

I don't think the workflow should update the tag though. It should fail and alert.

Actually having it automatically picked from the stable tag in README as an option would be better. I am aware there is another action for updating the readme, but it's not every plugin that one maintains tags for.
