TokenReview exists in two APIs but missing from config.refs

[jboxman]

So because reasons, TokenReview exists in two API groups, but is really the same. For some reason, there is no ref for #/definitions/io.k8s.api.authentication.v1.TokenReview such that it points to a file. It isn't clear why this is excluded:
