4.0.2: `pytest` is unable to setup tests

[mtelka]

The pytest is unable to find any tests in the sdist downloaded from PyPI:

$ wget https://files.pythonhosted.org/packages/source/i/invocations/invocations-4.0.2.tar.gz
$ gtar xf invocations-4.0.2.tar.gz
$ cd invocations-4.0.2
$ PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 pytest --setup-plan

This partially helps, but there is still some issue:

$ wget https://raw.githubusercontent.com/pyinvoke/invocations/refs/heads/main/pytest.ini
