CI Release Github Action is tagging wrong branch

Bug Report

Summary

Release CI workflow is tagging main even when releasing from a different branch/commit.
The build happens on the desired branch correctly, but a tag is then pushed on main and the release linked to that tag.

Details

It seems softprops/action-gh-release@v1 should be updated to v2 and that we should provide it with target_commitish if we wish to push a tag on a different branch.

Fix would be to:

• set target_commitish to the branch the workflow is being run on if it is not set
• add optional target_commitish input to workflow to allow tagging a specific commit
  • Update the rest of the workflow to use the passed target commit if set, to create the build based on that instead of latest commit.

This happened this morning while publishing 0.6.1 for the record. We found out the hard way. Surprising this wasn't noticed before.
