feat(manager/helmv3): support helm chart dependencies in OCI images

[secustor]

Changes:

Add support for parsing references using the oci:// protocol

Context:

Closes #11568

I didn't managed to get lockfile maintenance working. Not sure this is because I use podman or because I had to use other images as the image references provided by @ankitabhopatkar13 are not public

@secustor Really happy with such a fast response, thanks a lot!

I was trying to use this version of renovate-runner(3.17.0) on gitlab-ci. My helm charts are hosted in a private Gitlab Container Registry which is basically OCI based.

I was wondering if I can use the helm charts hosted in private Gitlab Container Registry. I saw the documentation here, tried to use the hostRules but I still get the following error -

{
                     "topic": "dependency-name",
                     "message": "Failed to look up dependency dependency-name"
                   }

I am trying to authenticate with Gitlab deploy token and the configuration looks like below -

  hostRules: [
    {
      hostType: 'docker',
      matchHost: process.env.CI_REGISTRY,
      username: 'ci-deploy-token',
      password: process.env.GITLAB_CI_CHARTS_DEPLOY_TOKEN,
    },

I also tried with token, but same error.

Thanks in Advance!
