Describe the bug
Similar issue to this comment : #8266 (comment)

When setting credentials templates that match a registry but that are not given as a repository (repocreds instead), the login fails because Argo CD passes the schema oci:// as the registry URL, but helm (using oras-go) will fail because it does not support the oci:// schema, and so login command will fail

To Reproduce

1. Create an ArgoCD helm OCI repo-creds secret

apiVersion: v1
kind: Secret
metadata:
  name: argoproj-gitlab-helm-creds
  namespace: argocd
  labels:
    argocd.argoproj.io/secret-type: repo-creds
stringData:
  url: registry.gitlab.com/test
  enableOCI: true
  type: helm
  password: my-password
  username: my-username

2. Use a chart with a dependencie that match the repo-creds url

apiVersion: v2
name: test-chart
version: 1.0.0
dependencies:
- name: toto-spa
  version: 1.1.1
  repository: "oci://registry.gitlab.com/test/toto"

3. ArgoCD will try to login with oci scheme in url

helm registry login oci://registry.gitlab.com/test/toto --username ****** --password ******

Expected behavior
helm registry login without oci scheme in url

helm registry login registry.gitlab.com/test/toto --username ****** --password ******
