Conversion errors in unit test logs

[sbueringer]

What steps did you take and what happened?

There are a lot of errors in the logs of our conversion unit tests (xref: https://storage.googleapis.com/kubernetes-jenkins/pr-logs/pull/kubernetes-sigs_cluster-api/8007/pull-cluster-api-test-mink8s-main/1654053928607682560/build-log.txt)

{"Time":"2023-05-04T09:26:31.736455585Z","Action":"output","Package":"sigs.k8s.io/cluster-api/exp/addons/api/v1alpha3","Test":"TestClusterResourceSetConversion","Output":"=== RUN TestClusterResourceSetConversion\n"} {"Time":"2023-05-04T09:26:31.832727542Z","Action":"output","Package":"sigs.k8s.io/cluster-api/exp/addons/api/v1alpha3","Test":"TestClusterResourceSetConversion","Output":"E0504 09:26:31.831850 19242 conversion.go:74] conversion-webhook \"msg\"=\"failed to convert\" \"error\"=\"no kind \\"ClusterResourceSet\\" is registered for version \\"addons.cluster.x-k8s.io/v1alpha4\\" in scheme \\"pkg/runtime/scheme.go:100\\"\" \"request\"=\"504bb6d6-33de-4392-85f8-5eff3be8c09d\"\n"}

Note: I'm talking about unit tests like TestClusterResourceSetConversion not the fuzz tests.

Basically we run v1alpha3 conversion tests and the error is that v1alpha4 is not registered. I don't really understand why there should be a conversion to v1alpha4. But this also doesn't fail the tests.

Would be interesting to figure out what's going on.

What did you expect to happen?
