fix(kubernetes): re-pin deleted centos:stream9 digest for kubevirt-csi-driver

quay.io/centos/centos:stream9 is a rolling tag; upstream deleted the pinned
digest (sha256:0c9db821...) when it published a new stream9 build, so every
build of image-kubevirt-csi-driver fails with "not found" — on open PRs and
on main. Re-pin to the current live stream9 digest (sha256:a93e3316...).

This is an emergency CI unblock, not a durable fix: stream9 is garbage-collected,
so upstream will delete this digest too on its next rebuild and the same
"not found" breakage recurs until the pin is bumped again — the same operation
Renovate's weekly, non-automerged digest PR performs. A durable fix (mirror the
base image into cozystack's own registry, or move to an immutable-digest base
such as UBI9) is out of scope for this hotfix and left as follow-up.
