py-test-cov: updated to 4.0.0

4.0.0 (2022-09-28)
------------------

**Note that this release drops support for multiprocessing.**

* `--cov-fail-under` no longer causes `pytest --collect-only` to fail
* Dropped support for multiprocessing (mostly because `issue 82408 \ 
<https://github.com/python/cpython/issues/82408>`_). This feature was
  mostly working but very broken in certain scenarios and made the test suite \ 
very flaky and slow.

  There is builtin multiprocessing support in coverage and you can migrate to \ 
that. All you need is this in your
  ``.coveragerc``::

    [run]
    concurrency = multiprocessing
    parallel = true
    sigterm = true
* Fixed deprecation in ``setup.py`` by trying to import setuptools before distutils.
* Removed undesirable new lines that were displayed while reporting was disabled.
* Documentation fixes.
* Added support for LCOV output format via `--cov-report=lcov`. Only works with \ 
coverage 6.3+.
* Modernized pytest hook implementation.
