OCI registry support in helm_import_repository

[marksmithson]

helm_import_repository does not support OCI registries.

both of the following result in exceptions.

helm_import_repository(
        name = "redis_helm",
        chart_name = "redis-cluster",
        repository = "oci://registry-1.docker.io/bitnamicharts/redis-cluster",
        sha256 = "9e9aae48b962c640c598630ef575a44ab7bb35015e1792f8544fb34c3b30bc57",
        version = "11.2.1",
 )

causes:
java.io.IOException: Bad URL: oci://registry-1.docker.io/bitnamicharts/redis-cluster/index.yaml

 helm_import_repository(
     name = "redis_helm",
     chart_name = "redis-cluster",
     repository = "not-requried-when-url-specified",
     sha256 = "9e9aae48b962c640c598630ef575a44ab7bb35015e1792f8544fb34c3b30bc57",
     url = "oci://registry-1.docker.io/bitnamicharts/redis-cluster:11.2.1",
 )

causes:
java.io.IOException: Bad URL: oci://registry-1.docker.io/bitnamicharts/redis-cluster:11.2.1

Is there another way to import charts from OCI registries?

Happy to help with a patch for this is needed - some pointers on where to start would be appreciated.
