Fix 3.11 test

[cdce8p]

Description

Not the ideal solution I was hoping for tbh, but it should work.
As suspected, the test failure is causes by python/cpython#92202. In particular, inside the __exit__ method there is the following assignment

def __exit__(self, typ, value, traceback):
    ...
    exc.__traceback__ = traceback

Previously, astroid couldn't infer __traceback__ and so defaulted to our fallback method.
https://github.com/PyCQA/astroid/blob/fd102d45a3552c00d951a07b02c49d278a7a69a2/astroid/interpreter/objectmodel.py#L644-L648
Now, with we have an assignment, which later gets inferred as Uninferable. However, that means we don't use the fallback anymore. I haven't quite figured out why an assignment in contextlib is applied to __builtins__.BaseException but that might be related the initial bootstrapping 🤷🏻‍♂️

Anyway, the test change should work and a fallback to Uninferable isn't the end of the world IMO.

Closes: #1551

Make sense, I'm not sure we'll even get regression in pylint for this.

I don't think so either. We can keep it in mind though if something does come up.
