Outdated CSINodeInfo CRD URL

[leakingtapan]

The URL for CSINodeInfo is outdated here:
https://kubernetes-csi.github.io/docs/Setup.html#enabling-csinodeinfo

It was:

https://raw.githubusercontent.com/kubernetes/csi-api/master/pkg/crd/testdata/csinodeinfo.yaml

Not it becomes:

https://raw.githubusercontent.com/kubernetes/csi-api/master/pkg/crd/manifests/csinodeinfo.yaml

Also, the same issue for CSIDriver CRD

Should we limit the use of URLs to the Example.md and just refer to it under Setup.md? If yes, then we only need to update URLs in one place. If no, then Setup.md should also start using URLs with a revision number.

Or we can keep the URLs centralized in Setup.md and refer to it from Example.md. It makes more sense to me to put it under setup, since this is more driver setup related. But I don't have strong opinion on this.
