tag: support arbitrary repositories in gpg_verify_tag()

Allow callers of gpg_verify_tag() specify the repository to use by
providing a parameter for that.  One of the two has not been using
the_repository since 43a8391 (builtin/verify-tag: stop using
`the_repository`, 2025-03-08); let it pass in the correct repository.
The other simply passes the_repository to get the same result as before.
