Remove port-forwarding in start_docker.sh

[zxia-wish]

This PR fixes an issue in config causing Docker to fail.

In short, port forwarding is not compatible with host network. See more here: https://docs.docker.com/network/host/

In addition, it may be a good idea to add a piece of documentation saying this shell script is not suitable for Docker Desktop, since the host networking is only available for Docker on Linux.
