fix(ci): create release tag when missing instead of only on version change

Auto Release now checks whether the tag for the current package.json
version exists on the remote; if not, it creates and pushes the tag.
This fixes the case where a version bump and other changes are pushed
in separate commits (e.g. version then changelog), so both HEAD and
HEAD~1 had the same version and no tag was created.
