COPR rawhide repo links

Dear rawhide users, if you have enabled a COPR repo in the last three months (since the beginning of December last year till yesterday), then it points to fedora-$releasever-$basearch. You can reenable it by using `dnf copr enable <project>` to get .repo file pointing to actual fedora-rawhide chroot in the given project. Sorry for this clime
