no support for tox v4

[graingert]

fails with:

  File "/home/graingert/projects/pytest-httpbin/.tox/.tox/lib/python3.10/site-packages/tox_wheel/plugin.py", line 6, in <module>
    import py
ModuleNotFoundError: No module named 'py'

then adding py I get:

  File "/home/graingert/projects/pytest-httpbin/.tox/.tox/lib/python3.10/site-packages/tox_wheel/plugin.py", line 7, in <module>
    from tox import package
ImportError: cannot import name 'package' from 'tox' (/home/graingert/projects/pytest-httpbin/.tox/.tox/lib/python3.10/site-packages/tox/__init__.py)

ah looks like wheels are supported out of the box https://tox.wiki/en/latest/upgrading.html#universal-wheels

Yeah. Might be time to archive this repo.
