[GEODE-10654] Publish multi-architecture release docker images

[JinwooHwang]

The release images were built with the default docker driver, which produces an image only for the host architecture. Releases cut on an arm64 machine therefore published arm64-only images, which cannot run on amd64 hosts.

Build with a container-driver buildx builder and push a manifest covering linux/amd64 and linux/arm64. A multi-platform result cannot be loaded into the local image store, so the tagged image is now built and pushed in a single step.
