Add a new exception for CO's Available=False in non-upgrade tests

OCPBUGS-23746 has been an exception [1] for CO/openshift-apiserver's
Available=False in upgrade tests.

Now it is identified in non-upgrade tests too [2]. This pull acts
on it accordingly.

Although we found `APIServices_Error` as the only reason at the moment,
others get duplicated here as well for less disruptions for the payload
tests.
