Fix 'repomd.xml signature could not be verified' (#35989)

If a repo with `repo_gpgcheck=1` is added and the repo GPG key was never
accepted, quering this repo would throw an error `repomd.xml signature
could not be verified` and the module would fail. If that happens now
`yum -y makecache` will be run which will fetch the new repo data and
accept the repo GPG key.
