Backport #20893
In the compare endpoint the git fetch is restricted to a certain branch however,
this does not completely prevent tag acquisition/pollution as git fetch will collect
any tags on that branch.
This causes pollution of the tag namespace and could cause confusion by users.
This PR adds `--no-tags` to the `git fetch` call.
