Fix protobuf CI publish jobs
Part of #3 (closed)
See: #3 (comment 806532)
Attempts to fix:
- The
protobuf:publish:python:gitlabjob is not running - The
python:publish-to-gitlabis running where it shouldn't
And a workaround for:
- In the GitLab release, the version number of the message schemas python library does not match the version number of the release
By switching to the release-it merge request flow.
