Docker workflow dispatch on branches does not work with custom tags

[Rjected]

I tagged the branch I was working on in #144 as fdaa810b, ran the docker push action (here /~https://github.com/ithacaxyz/odyssey/actions/runs/13559523460), which failed on the git describe step with:

fatal: No names found, cannot describe anything.

Meaning it got tagged as latest, instead of the tag I set in git. This would have been useful for pushing images with commit hash tags, so we can pull and test specific non-release commits

Even though locally I get:

git describe --tags
fdaa810b
