seems documentation is few commits behind. you should be able to fix this by setting an env var DOCKER_PLATFORM to whatever platform you want to build on. this might either be linux/amd64 or linux/arm64.
e.g.
$ DOCKER_PLATFORM="linux/amd64" docker-compose build sandbox

$ export DOCKER_PLATFORM="linux/amd64"
$ docker-compose build sandbox
