update gh workflows for multi arch build (#612)

Add support to build images for linux/arm64, linux/amd64

From the Docker documentation: QEMU and Docker Buildx 
needed to be setup in the workflow to build multi-arch images.

The documentation suggests using the docker/build-push-action@v5 
action to build multi-arch images.

Fixes #163
