Define Dockerfile with AM64 platform on M1 Apple

Time over time I’m building docker images that can only be run on x64. To force M1 Mac

1. FROM --platform=linux/amd64 ubuntu:22.04
2. export DOCKER_DEFAULT_PLATFORM=linux/amd64
3. In docker compose ```yaml services:
   frontend:
   platform: linux/amd64 build: frontend
   ports:
   • 80:80
     depends_on:
   • backend
     backend:
     platform: linux/amd64 build: backend
     ```
4. docker buildx build --platform linux/amd64 .
