Fix Fedora IoT upgrades when packages are layered

I recently installed Fedora IoT on my home server. I layered packages on it.

Recently an upgrade attempt failed resulting in multiple cannot install both messages.

I stumbled upon this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1928326

The solution is to add the fedora-updates-archive repository. For instance, for Fedora 39:

sudo sh -c "curl https://src.fedoraproject.org/rpms/fedora-repos/raw/f39/f/fedora-updates-archive.repo > /etc/yum.repos.d/fedora-updates-archive.repo"

rpm-ostree upgrade should now works everytime 🤗
