Provide helm chart via OCI registry

[mardonner]

Is your feature request related to a problem? Please describe.

Helm made the OCI registries feature GA with v3.8.0. I'm currently transitioning all charts that I use to this registry type if available. Atm no particular reason other then trying out the new feature.
I noticed that you currently don't publish this chart on an OCI registry like ghcr,io.

Describe the solution you'd like

Make the chart available on ghcr.io or some other oci registry.
Make sure to set the repo to public access. Noticed some having it intially set to private after adopting oci registries.
So that I can run smth like:

helm pull oci://ghcr.io/stackitcloud/charts/stackit-cert-manager-webhook:0.3.5
# or
helm template oci://ghcr.io/stackitcloud/charts/stackit-cert-manager-webhook:0.3.5

Example of external-secrets doing this.

Describe alternatives you've considered

OCI is not a must for me. The current distribution method works fine.
