build: Update CRDs and k8s dependencies

[colunira]

CRDs in version v1beta1 are deprecated. Update the version to v1 and bump k8s dependencies.

• Changed rule compare logic: the SelfLink attribute in ObjectMeta is no longer used, switched to UID.

Hi there, and thanks for your contribution ;) PR related to ory/k8s#236
Could you also update the version of kind? The current one is installing k8s 1.17.

[Demonsthere]

Since you changed the required go version, please update it also in the CI config otherwise, it won't be able to run

[colunira]

Thanks for the advice ❤️
I will update kind, too

It looks like in the test, here the CM is empty, instead of having 1 item
