Unable to run tests

Hi, I'm working on a PR but first I'd like to make sure I can get all tests running. I followed all of the instructions in the For Developers, Pre-commit hooks, and Running the tests section of the README. When I run the command python setup.py pytest I get the following:

(econml) C:\Users\ronik\Desktop\EconML>python setup.py pytest
C:\Users\ronik\anaconda3\envs\econml\lib\site-packages\ptr\__init__.py:81: SetuptoolsDeprecationWarning: The test command is disabled and references to it are deprecated.

        ********************************************************************************
        Please remove any references to `setuptools.command.test` in all supported versions of the affected package.

        By 2024-Nov-15, you need to update your project and remove deprecated calls
        or your builds will no longer be supported.

AttributeError: 'Distribution' object has no attribute 'tests_require'

This is with python 3.8.x. Any suggestions?

Start with the README's “For Developers, Pre-commit hooks, and Running the tests” section and inspect setup.py alongside the reported python setup.py pytest traceback. Check how the ptr test command handles tests_require under Python 3.8. Done means the documented command runs without the Distribution AttributeError and executes the test suite.
