Build arm and arm64 versions of the docker container.

[gheydon]

Currently the build is only the amd64 version of the container. And I am not sure if this is built automatically.

See https://github.com/heydon-consulting/drupal-builder/blob/d58730e5dddc8d4f6aaf78bb7f803c8180a4eb8c/.github/workflows/build.yml#L42-L55 for an example on using the workflow to build docker images and push them automatically.

I currently have a Raspberry Pi in my garage to be close to my car. I had to build the docker image locally do I could deploy it. Having a full pc is not really an option just to build download the files from the dashcam.
