Require docker on the machine in docker-tests

So we can move away from years old docker-compose and docker package that limits the other dependencies like requests < 2.32.0. And maybe also Python version. tox `docker-tests` environment already assumes a debian based distribution so we can install the `docker.io` package (and docker-compose-v2 on ubuntu) if the `docker` command is not available and switch to `docker compose` subcommand.
