[lspecian-olx]

Description The apiextensions.k8s.io/v1beta1 apiVersion used in the CustomResourceDefinition was removed on k8s v1.22.0

Importance The issue is a blocker to install the chart properly on k8s clusters with version v1.22.0

Suggestions for an improvement I suggest the issue should be fixed by checking the apiVersion with .Capabilities.APIVersions.Has

{{- if .Capabilities.APIVersions.Has "apiextensions.k8s.io/v1" }} apiVersion: apiextensions.k8s.io/v1 {{- else }} apiVersion: apiextensions.k8s.io/v1beta1 {{- end }}
