Update gpgkey path in fedora-46.repo, drop unused fedora-45.repo

Update gpgkey path in fedora-46.repo from /etc/pki/rpm-gpg/ to
/usr/share/pki/rpm-gpg/ for the F45 GPG key relocation.

See: https://discussion.fedoraproject.org/t/f45-change-proposal-relocate-rpm-repo-configs-to-usr-selfcontained/188916

Remove fedora-45.repo from main (rawhide) - it belongs on f45-branch.
