[Bug]: Add ARM platform to GitHub actions for docker build

[cwysong85]

What happened?

It would be nice if you could support building for arm platforms in your GitHub build workflow.

example build (could potentially use this right away in your script, but there's other ways of doing it too):

docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 [rest of tagging commands]

Relevant log output

Looks like your release workflow uses the run command which is OK but swapping the run command for the uses command with actions might make this easier:

name: Release

on:
  push:
    branches:
      - main

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - name: Login to Docker Hub
        uses: docker/login-action@v3
        with:
            registry: ghcr.io
            username: ${{ github.actor }}
            password: ${{ secrets.GITHUB_TOKEN }}

      - name: Set up QEMU
        uses: docker/setup-qemu-action@v3

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Build and push
        uses: docker/build-push-action@v6
        with:
          platforms: linux/amd64,linux/arm64
          push: true
          tags: ghcr.io/${{GITHUB_REPOSITORY}}:latest
