ci: Use Fedora latest instead of rawhide temporarily

The pipeline currently fails with Fedora rawhide, because g-ir-scanner fails
with failures like: "ldd: error: you do not have read permission for
`/builds/GNOME/nautilus/_build/tmp-introspectgwhh729q/Nautilus-3.0'".
This obviously affects more projects:, e.g. GNOME/grilo!62. Let's use
Fedora latest for now as a workaround.
