OCI Helm Repositories are always displayed as false #511

Expected behaviour

If there is no error in the status, the icon for OCI repositories should be a green checkmark

Actual behaviour

When including Helm Repositories that point to OCI Registries, the extension always marks them as failed because they return no status

Steps to reproduce

deploy a helm repository that uses an OCI registry.
Example:

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: bitnami-charts
  namespace: flux-system
spec:
  type: oci
  interval: 1m0s
  url: oci://registry-1.docker.io/bitnamicharts

result:
