RichHandler Inheritance Issue

[AndTheDaysGoBy]

Description

I was recently trying to use pip-tools to generate a requirements.txt. This failed, debugging yielded that the issue lied in

venv/lib/python3.8/site-packages/piptools/repositories/pypi.py", line 455, in _setup_logging
    assert isinstance(handler, logging.StreamHandler)

Apparently, the RichPipStreamHandler was no longer being recognized as a type StreamHandler.

In particular, this issue only arose from pip==22.0 onwards, this was not present in pip==21.3.1.

I'm using Python 3.8, for reference.

Expected behavior

For the RichStreamHandler to be see as an instance of type StreamHandler such that the assert succeeds.

pip version

22.0+

Python version

3.8

OS

Linux (Tried on CENTOS and Mint)

How to Reproduce

1. Create a virtual environment.
2. pip -U install pip==22.0 or 22+
3. pip install pip-tools or anything that might use the RichStreamHandler
4. For this case, pip-compile -r requirements.in where we have echo "connexion2 > requirements.in for example.
5. It'll error on the assert is instance of.

Ah, I see, thank you.

Bit surprised that the Rich Stream Handler isn't instance of Stream Handler, but I guess that's a "types" vs "classes" situation.
