feat: Add tests with higher version skew for compatibility version

[michaelasp]

Now that the alpha.1 tag has been cut for K8s, we have had emulated version added for 3 releases. Add tests for that use case as the KEP states that we should be able to support up to N-3 version skew for emulated versions.

Hi @michaelasp. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
