Anchor the full privileged-group regex.
system:serviceaccounts:default-evil matches the default alternative because the expression has no final $. The authorization path in pkg/webhooks/networkpolicies/networkpolicies.go:69-120 uses this match to allow NetworkPolicy operations in managed namespaces and openshift-ingress. Add an end anchor to the full expression and a negative test for this group.
As per path instructions, “Normalize Unicode and anchor regexes (^$); watch for ReDoS.”

Summary
Adds
opendatahubto thePrivilegedServiceAccountGroupsregex so thatsystem:serviceaccount:opendatahub:maas-controller(and other SAs in theopendatahubnamespace) can create NetworkPolicies inopenshift-ingress.With OCP 4.22's deny-all NetworkPolicy in
openshift-ingress(NE-2501),operators deploying pods into that namespace must create explicit allow
NetworkPolicies. PR #581 added the privileged SA check to the
openshift-ingresscode path, but theopendatahubnamespace was notcovered by the existing regex.
Changes
pkg/webhooks/utils/utils.go: Addedopendatahub$to the privilegedservice account groups regex. The
$anchor ensures only the exactnamespace matches (not
opendatahub-other, etc.)pkg/webhooks/utils/utils_test.go: Added regex unit tests verifyingexact match and rejection of prefix/suffix variants
pkg/webhooks/networkpolicies/networkpolicies_test.go: AddedopendatahubServiceAccount()test helper and tests for:openshift-ingresswithout theingress controller label
