URL redirect for centos stream does not work correctly

[thrix]

It would be great if this:

❯ curl https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/repo/centos-stream-$releasever/rhcontainerbot-podman-next-centos-stream-$releasever.repo
[copr:copr.fedorainfracloud.org:rhcontainerbot:podman-next]
name=Copr repo for podman-next owned by rhcontainerbot
baseurl=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/centos-stream-10-$basearch/
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1

Would return a generic copr repo with $releasever (as for Fedora):

❯ curl https://copr.fedorainfracloud.org/coprs/rhcontainerbot/podman-next/repo/centos-stream-$releasever/rhcontainerbot-podman-next-centos-stream-$releasever.repo
[copr:copr.fedorainfracloud.org:rhcontainerbot:podman-next]
name=Copr repo for podman-next owned by rhcontainerbot
baseurl=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/centos-stream-$releasever-$basearch/
type=rpm-md
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://download.copr.fedorainfracloud.org/results/rhcontainerbot/podman-next/pubkey.gpg
repo_gpgcheck=0
enabled=1
enabled_metadata=1
