Publishing to pypi doesn't work because of missing tags

[cmutel]

The official documentation recommends using startsWith(github.ref, 'refs/tags/') to see if there is a release, and we follow this practice. However, it no longer works, or at least not consistently.

Running echo ${{ github.ref }} on a tagged release now gives refs/heads/main, at least in my testing.

Alternatives to this practice:

• Use github.event.release.tag_name or just triggering on the "publish" event. Would require triggering release events.
• Using tags that always start with v, combined with a reliable way to get the tag name.

Workaround for now is to push to pypi manually. The testpypi action runs fine.
