The current GitHub Actions workflow builds and pushes separate Docker
images for each registry. This results in the images published to each
registry having a different hash, despite having the same version tag.

This change modifies the Docker publishing job in the release workflow
so that a single step builds and publishes the same Docker image to all
Docker registries. For reproducability, the timestamp of the image is
also set to the last commit timestamp.

Instead of relying on QEMU emulation to build multi-arch images, use
native arm64 and amd64 build runners to build architecture-specific
images, then publish multi-arch metadata with each of the image
manifests.
