rbac.authorization.k8s.io/v1beta1 is no longer used

[dghg]

When i run this tutorial with qwiklabs.. i found that make create exit with error.

Cause

With repository's terraform configuration, it creates v1.22.x k8s cluster now.

and manifests/rbac-setup.yaml used the rbabc.authorization.k8s.io/v1beta that is not served in version 1.22!
