new pytest version throws deprecation warning

[Jasha10]

Earlier today, pytest v7.0.0 was released. With this new pytest version installed, running pytest --nbval my_notebook.ipynb throws a deprecation warning:

E   pytest.PytestRemovedIn8Warning: The (fspath: py.path.local) argument to IPyNbFile is deprecated. Please use the (path: pathlib.Path) argument instead.
E   See https://docs.pytest.org/en/latest/deprecations.html#fspath-argument-for-node-constructors-replaced-with-pathlib-path

Here is the full traceback for the warning:
