/kind cleanup

What this PR does / why we need it:

# 1. In k8s 1.24, the following example command returns nothing, because the extensions/v1beta1  API versions of Ingress is no longer served as of v1.22.
$ kubectl api-resources --api-group=extensions
NAME   SHORTNAMES   APIVERSION   NAMESPACED   KIND

# 2. Compare with k8s 1.20.15.
$ kubectl api-resources --api-group=extensions
NAME        SHORTNAMES   APIVERSION           NAMESPACED   KIND
ingresses   ing          extensions/v1beta1   true         Ingress

# 3. I think the example help command should be updated, I chose rbac.authorization.k8s.io because this API is relatively stable and is installed by default.
$ kubectl api-resources --api-group=rbac.authorization.k8s.io
NAME                  SHORTNAMES   APIVERSION                     NAMESPACED   KIND
clusterrolebindings                rbac.authorization.k8s.io/v1   false        ClusterRoleBinding
clusterroles                       rbac.authorization.k8s.io/v1   false        ClusterRole
rolebindings                       rbac.authorization.k8s.io/v1   true         RoleBinding
roles                              rbac.authorization.k8s.io/v1   true         Role
