Build images for multiple platforms #35
Description
This is part of an ongoing series of issues we run into every now and again, when trying to pull/build this image in a local environment on a new architecture (e.g. Mac M3).
We think the solution is to have the publish.yml workflow build the Docker image for multiple platforms, following the advice from this Docker article: https://docs.docker.com/build/ci/github-actions/multi-platform/
We need to build for at least 2 platforms:
linux/amd64for Windows and Linux devslinux/arm64for Mac devs on Apple Silicon
Once this change is in and the docker-python-web image is rebuilt into GHCR, devs on all architectures should be able to pull and run this image, and should be able to build e.g. the benefits_client image locally, which is based on this image.
