Publish CRD chart as a standalone helm chart

[aslafy-z]

Is your feature request related to a problem? Please describe.
My org prefer to install CRDs in another low number wave with ArgoCD.

Describe the solution you'd like
I'd like the CRD subchart to be available as an OCI artefact like the original chart is.

Describe alternatives you've considered
I'm currently installing them with kustomize like:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: k8saas-system
