Kubernetes GKE example does not work

[susanev]

this came in by way of docs feedback

while the user was on this page: https://www.pulumi.com/registry/packages/kubernetes/how-to-guides/gke/

failed to initialize discovery client: The gcp auth plugin has been removed

im opening here because its an example, but it is a hand-authored example that has not been moved to this repo yet https://github.com/pulumi/registry/edit/master/themes/default/content/registry/packages/kubernetes/how-to-guides/gke.md

@cnunciato Since #1435 was closed (and given the reason provided for closing it), does that mean this one needs to be closed as well?
