[chart/redis-ha][BUG] can't pull oci helm chart with helm pull - 401 unauthorized

[mardonner]

Describe the bug

Cant' pull oci helm chart for redis-ha with helm pull - getting a 401 unauthorized

To Reproduce
Steps to reproduce the behavior:

helm pull oci://ghcr.io/dandydeveloper/charts/redis-ha
Error: GET "https://ghcr.io/v2/dandydeveloper/charts/redis-ha/tags/list": GET "https://ghcr.io/token?scope=repository%3Adandydeveloper%2Fcharts%2Fredis-ha%3Apull&service=ghcr.io": unexpected status code 401: unauthorized: authentication required

Expected behavior
Expected successful pull like with the helm oci chart for external-secrets

helm pull oci://ghcr.io/external-secrets/charts/external-secrets:0.14.2
Pulled: ghcr.io/external-secrets/charts/external-secrets:0.14.2
Digest: sha256:39d173fdec69178d4f72912a0e6bf0ef573523378e8e710f1aca4efcd050690a

Additional context
As per #303 I thought it'd be possible to download the oci helm chart. However, it seems like the gchr.io repo is not set to public.

@mardonner I'll take a look at this tomorrow. I haven't really made any considerations for OCI, so the registry is probably neither live nor public.
