Build docker images for amd64, arm64, and arm/v7. Also several other small improvements to docker workflow like documenting which actions we run on, setting concurrency settings, and reversing the logic for when we push new images live (specifically looking for a push event rather than a "not pull request" event, in case we add other events later). Fixes #26
