What happened + What you expected to happen

When building multi-platform Docker images in our GitHub Actions workflow using docker/build-push-action@v5, the workflow fails with the following error:

ERROR: Multi-platform build is not supported for the docker driver.
Switch to a different driver, or turn on the containerd image store, and try again.

Ref: https://github.com/ray-project/kuberay/actions/runs/14912974191/job/41891655016

This because The default docker/setup-docker-action does not support loading multi-platform images to the local image store of the runner after building them. To load a multi-platform image, you need to enable the containerd image store option for the Docker Engine.

We can choose one of the following two approaches:

1. Enable containerd image store in the Docker daemon

- name: Set up Docker
  uses: docker/setup-docker-action@v4
  with:
    daemon-config: |
      {
        "debug": true,
        "features": {
          "containerd-snapshotter": true
        }
      }

Ref: https://docs.docker.com/build/ci/github-actions/multi-platform/#build-and-load-multi-platform-images

2. Or switch to use docker/setup-buildx-action
