GHSA-jhjp-4c2q-xmx4: k8saudit shipped rules do not detect privileged/sensitive settings on init or ephemeral containers

The k8saudit plugin’s per-container fields (ka.req.pod.containers.*) and the shipped k8s_audit_rules.yaml evaluated only requestObject.spec.containers. Security-relevant settings on a pod’s initContainers or ephemeralContainers were not inspected, so the shipped Create Privileged Pod rule did not fire for a privileged container placed in either list.
