ci: override existing snapshot tag if publish snapshot job is restart…

…ed (#46366)

If the snapshot publish job is manually being restarted, the tag in the
snapshot repo might already exist and the job will fail. We can just
forcibly re-create the tag (even if it will be at the same revision).

We use force mode in a couple of other command as well, such as `git
push` of the actual tag and snapshot revision/SHA.
