ci: cache: Use the cached artefacts from ORAS

In the previous series related to the artefacts we build, we've
switching from storing the artefacts on Jenkins, to storing those in the
ghcr.io/kata-containers/cached-artefacts/${artefact_name}.

Now, let's take advantage of that and actually use the artefacts coming
from that "package" (as GitHub calls it).

NOTE: One thing that I've noticed that we're missing, is storing and
checking the sha256sum of the artefact.  The storing part will be done
in a different commit, and the checking the sha256sum will be done in a
different PR, as we need to ensure those were pushed to the registry
before actually taking the bullet to check for them.

Fixes: #7834 -- part 2
