fix: Do not hoist identical version schemas for apiextensions.k8s.io/v1

[project0]

The underlying k8s api that converts into the final CRD object is deduplicating versions.

With rehydrating the schemas we fix a problem with possible API incompatibility and the generated specs.

the underlying k8s package/method call apiextv1.Convert_v1_CustomResourceDefinition_To_apiextensions_CustomResourceDefinition(crdObj.(*apiextv1.CustomResourceDefinition), crd, nil)
is preventing export of schema versions with same properties.

looks like the tests are very flaky:

could not resolve schema: unexpected end of JSON input

[Peefy]

Yes. I will merge this PR firstly. It's the CI issue.
