Test has been flakey Image failing since it started on Apple Silicon. Updated the test expectations to Pass ImageOnlyFailure here:

https://trac.webkit.org/changeset/274681/webkit

Failure is only occurring on Apple Silicon systems, and as such I cannot duplicate the failure because I do not have access to one.
