`apiextensions.k8s.io/v1beta1` no longer supported in Kubernetes 1.22

[spowelljr]

Hello, we have Ambassador as one of the addons in minikube.

The problem is we updated the default version of Kubernetes to 1.22 as that's the latest GA release, however in that release they stopped supporting apiextensions.k8s.io/v1beta1 which is still in use here https://github.com/datawire/ambassador-operator/blob/master/deploy/crds/getambassador.io_ambassadorinstallations_crd.yaml.

Unfortunately on our latest release of minikube (v1.23.0) the Ambassador addon is no longer working.

More details about the deprecation can be found here: https://kubernetes.io/docs/reference/using-api/deprecation-guide/#customresourcedefinition-v122

Thank you

FYI, Ambassador has been renamed to emissary-ingress: https://www.cncf.io/blog/2021/04/13/emissary-ingress-formerly-ambassador-is-now-a-cncf-incubating-project/
