Limit release trigger to 0.* tags (#14940)

This changes the release trigger to only run when a tag matching the
pattern `0.*` is created. The intent is to allow us to create tags for
other crates that we may release out-of-band of the normal releases (and
maybe consider creating tags for all crates to make them easier to
find). For example, I would like to create `home-0.5.11` tags (and
earlier versions that were missed due to this trigger).
