refactor: determine docker compose command based on system

- Determine whether to use `docker compose` or `docker-compose` based on whether
  the former is available on the system at hand.
- Use the `--remove-orphanS` flag, supported since v1.7.0, instead of its
  singular form which was removed at some point.
