    Fix functional tests and docs generation

    First, fix test_help(). A commit[1], which first appeared in Python
    3.10, changes the output of the help feature of argparse. Options used
    to be in a section named "Optional arguments:", and they are now in a
    section named "Options:".

    Second, tox 4 changes the behaviour of tox, and
    {toxinidir}/requirements.txt is no longer installed automagically in the
    docs virtual environment. This causes autodoc to fail on some imports.
    We explicitely add {toxinidir}/requirements.txt to the list of
    dependencies to fix this issue.

    These issues should be fixed in separate patches, but since they both
    block the CI, they depend on each other.
