cssnr/stack-deploy-action: registry authentication not working for private repositories without additional configuration

[guilhermeprokisch]

For private repositories, additional registry authentication arguments are required for the --with-registry-auth flag to work properly with the stack-deploy-action.

The following registry configuration needs to be added:

- name: Docker Stack Deploy
  uses: cssnr/stack-deploy-action@v1
  with:
    name: zenfulstats
    file: docker-stack.yaml
    host: zenful.site
    user: deploy
    ssh_key: ${{ secrets.DEPLOY_SSH_PRIVATE_KEY }}
    env_file: ./envfile
    registry_auth: true
    registry_host: "ghcr.io"
    registry_user: ${{ github.actor }}  # or your specific GitHub username
    registry_pass: ${{ secrets.GITHUB_TOKEN }}  # or ${{ secrets.USER_PAT }}
