Issue details

If we have insecure registry (e.g. harbor installed in minikube) - we can not install helm chart "oci://" because it is using https://

The error will be Error: Get "https://.../v2/.../tags/list": http: server gave HTTP response to HTTPS client

There is an option in helm --plain-http https://helm.sh/docs/helm/helm_install/

Please do implement
