Migrate to docker compose V2

[sepulzera]

Reported by CorvusGei:

With up to date Docker installations the script has to be edited to use "docker compose" instead of "docker-compose".
So quick-start.py should be updated to this. Thanks!
And maybe there's an option to use sudo? (Maybe detect , if the script is running as root and else use sudo docker compose?)

docker-compose V1 is going EOL:

From the end of June 2023 Compose V1 won’t be supported anymore and will be removed from all Docker Desktop versions.

(https://docs.docker.com/compose/install/linux/)

Probably only the docs and quick-start.py need to be updated. Though it should be veryfied that everything is still working as expected.
