Option to use another docker registry than Docker Hub about builder

[agners]

The string will be passed to the Docker command line directly as the container repository part of the image name directly. So you should be able to use the GitLab registry just fine with that flag.

Does not work for me, it's failing at the login part.

My command line: docker run --rm --privileged -v ~/.docker:/root/.docker -v $(pwd):/data homeassistant/amd64-builder --aarch64 -t /data --docker-hub registry.<redacted> --docker-user <redacted> --docker-password <redacted>

The error: Error response from daemon: Get "https://registry-1.docker.io/v2/": unauthorized: incorrect username or password

At https://github.com/home-assistant/builder/blob/master/builder.sh#L956, the registry is not passed to the docker login command, so docker hub is used.

Sorry for the lack of information in my issue.

@MexHigh If you do not provide --docker-user and --docker-password, but manually run the correct docker login command before, it will work. I use this in my addons-repo to push to ghcr.io
