🐛 Add ClusterExtensionRevision permissions to upgrade test RBAC

ClusterExtensionRevisions when BoxcutterRuntime is enabled.
Without these permissions, the upgraded controller cannot create
or update ClusterExtensionRevision resources, causing the
ClusterExtension to fail reconciliation after upgrade.
