branch-update-repo: Properly handle branching a stable release

Stable releases are special as the the name is very similar to the preview
one. To properly check if the repo was already branched the check should
be done using full words and not only parts, if not the match will always
be true.

As a real example, when branching v2025 from v2025pre the check for v2025
will true as if not using full words.
