(tylerslaton): Check CRDValidator safe storage logic

[github-actions]

This test is currently trying to simulate a situtation where an incoming

CRD removes a stored version. However, it does not work as expected because

something (potentially the apiserver) is intervening first and not allowing

it through. This is fine and ultimately what the safe storage logic of the

CRDValidator was designed to prevent but is unknown why it is occurring. We

Should come back to this test case, figure out what is preventing it from

hitting the webhook and decide if we want to keep that logic or not.
