install-deps.sh: add a temporary repo for missing el10 deps

Add a new dnf/yum repository hosted in the ceph lab infra for providing
the last few dependencies missing from other el10 repos.
Hopefully we can remove this soon but it serves as a stopgap as we work
on getting el10 builds working in the ceph CI infra and tested.
