The expected results are from Fedora rawhide.

Specifically, I don't need libdnf5 (dnf5) on Fedora 38 to be updated to 5.1 as is on rawhide, the 5.0 is just fine, but the installation should be developer-friendly. One of the reasons is that microdnf on Fedora 38 is now just dnf5, so we are being pushed to dnf5 that way.
