PackageRevision label selection does not work

[johnbelamaric]

Expected behavior

I can use kubectl get packagerevision -l 'kpt.dev/latest-revision=true' to see the latest version of the packages.

Actual behavior

All package revisions are returned. I suspect this is because it's an aggregated API server so we would have to implement this ourselves (maybe another reason to use CRDs instead):
