ci: Build multi-platform image with cross-compilation

The previous build workflow used emulation to build the Docker image,
which results in a somewhat complicated push-by-digest and merge
workflow to create a multi-platform image.

This commit changes the Docker build to use cross-compilation instead,
resulting in a faster and more straightforward build.
