Set lower bound on docker version

[naomielst]

From my experience, the docker version must be >= 4.0.0

This will also need a rebuild of the requirements (cf. #188). The motivation behind completely pinning down the requirements for tests is to be able to separate "issues caused by dependency versions changing" from "issues introduced in a PR".

I suggest using something like poetry instead and caching the lock file.

Yup, those requirements are locked down dependencies. We just generate them using pip-tools rather than poetry or pipenv.

@tillahoffmann Would you mind doing it this time?
