Test failing in windows 11 using master branch

When running setup.py test on my Windows 11 Pro computer (version 22H2) in the master branch of pipreqs, I got the following error:

```
======================================================================
FAIL: test_init_local_only (tests.test_pipreqs.TestPipreqs.test_init_local_only)
Test that items listed in requirements.text are the same
----------------------------------------------------------------------
Traceback (most recent call last):

AssertionError: False is not true`

I basically followed the "_Get Started_" section of the CONTRIBUTING page, but I installed virtualenvwrapper-win 1.2.7 instead of the Linux version.

Reproduce the failure with `setup.py test` on Windows 11, then inspect `tests/test_pipreqs.py` around `test_init_local_only` and line 141. Determine why the expected requirements entries differ on Windows; done means the test passes without regressing the existing suite.
