fix: 600GB openedx-dev image on macOS

On macOS, building the "openedx-dev" Docker image resulted in an image that required more than 600 GB of disk space. This was due to the `adduser` command which was called with a user ID of 2x10⁹ (on macOS only). This resulted in a very large /var/log/faillog file, hence the image size.
