Issue:
tox doesn't install simple_menu in GH Actions
First arisen in [the workflow](https://github.com/jazzband/django-simple-menu/actions/runs/3933403219/jobs/6727068432) for #122. It seems like tox doesn't install `simple_menu` for some reason.

Compare the dependency step of [the succeeded py36-dj32 run](https://github.com/jazzband/django-simple-menu/actions/runs/3933403219/jobs/6727068372#step:7:28) versus [the failed py37-dj32 run](https://github.com/jazzband/django-simple-menu/actions/runs/3933403219/jobs/6727068432#step:7:24).


Discussion / hints:
Probably has something to do with tox v4 release: https://tox.wiki/en/latest/upgrading.html as it doesn't occur on Python 3.6 which doesn't support tox 4
