No version needed in docker-compose.yml and updates to reflect latest changes in the docker ecosystem

Thanks for the awesome description and work on the Dockerfiles / Docker compose files! Really appreciated it!

As Docker Captain I am always looking at the Docker parts of a project and will try to improve them. Just one very very little thing.

The version in your docker-compose.yml is now optional can be omitted. Furthermore the docker-compose.yml should now be compose.yml.

Last but not least the docker-compose up command should now be docker compose up. I am happy to submit a PR if you are open for that. As said JUST very small changes to reflect the latest updates in the Docker ecosystem.

Thanks for the great work!
Cheers
