When we're tagging a version that's not the latest version, then don't
update the `latest` Docker image on Docker hub. Like, if the current
latest is `v1.20`, and we publish the hotfix tag `v1.18.1` to fix a
critical bug in `v1.18`, then we only want to publish the Docker image
at the tag `v1.18.1`, and _not_ update `latest`. We want `latest` to
continue to point to `v1.20`.
Tested on a separate private repo, confirmed working.
