migrate to new docker compose cmd

[Cerchie]

Description

Update docker-compose to docker compose. Update docker-compose.yml to canonical compose.yaml.

What behavior does this PR change, and why?

docker-compose is the V1 version of the command and V1 is unsupported and risky. I made the main change and checked for the different commands outlined in the linked guide.

Note: You can create an alias like so:

sudo touch bin/docker-compose
echo 'docker compose --compatibility "$@"' | sudo tee /usr/bin/docker-compose
sudo chmod +x bin/docker-compose                                        

But this is an unsatisfactory experience.
