Update CI to check and abort publishing if an image with the same tag exists.
Why it needs to get done
Since a publish job can be triggered on dispatch, it is possible it will try to publish an image with a tag while there is already one published.
We should update our publish workflows (one is here) in order to make sure our CI protects us from this, since this is a mistake that can happen in silence.
