Update testdata for CRD v1

This updates the testdata for CRD v1.  All the changes are just
description wrapping.  We only test generation of CRD v1, since we now
rely entirely on the k/apiextensions-apiserver conversion logic to do
the hoisting of the common versions (and have separate tests for that).
