[Centos-automotive-sig] NOTICE: osbuild copr change for sample-images

The sample-images images used to rely on the @osbuild/osbuild copr repo, which is a development snapshot of osbuild. Starting today we now rely on the new @osbuild/osbuild-stable repo instead which only has the latest stable release in it.

All users of sample-images are recommended to switch to this new copr, and all the internal references in sample-images (such as the devel image) has been changed.

To switch, do something like: $ sudo dnf copr disable @osbuild/osbuild $ sudo dnf copr enable @osbuild/osbuild-stable $ sudo dnf update
