Circle back on pytest.PytestUnraisableExceptionWarning

[schuylermartin45]

We currently suppress some pytest.PytestUnraisableExceptionWarning warnings in the .pytest.ini file.

We should do a deeper dive to ensure this will not impact users. This seems to show up in both the Python 3.11 and 3.12 tests.

ValueError: I/O operation on closed file.

NOTES

• This seems tied to the complex mockers used in the fetcher module. May also be related to our pyfakefs usage?
