Willjianger9 57d89c25aa Add fallback to CONTAINER_DEFAULT_PLATFORM for image architecture (#1286)
- Closes #1252 (part of #913).
- Commands that accept `--platform` currently require it
  to be passed explicitly every time. Users working
  consistently with a non-native platform (e.g. `linux/amd64`
  on Apple Silicon) have no way to set a default, unlike
  Docker's `DOCKER_DEFAULT_PLATFORM`.
- This adds support for the `CONTAINER_DEFAULT_PLATFORM`
  environment variable as a fallback when `--platform` is not
  explicitly provided.
