[PATCH] Use pre-Python 3.13 Generator type syntax in conftest.py

[Artur Weber <aweber.kernel@gmail.com>]

Python 3.13 defaults to None for the other fields of the Generator type,
but the version of Generator in older versions does not support such syntax.
Explicitly add the missing fields to allow the tests to run on older Python
versions.

(An alternative solution would be to use typing-extensions for older
versions, though that would require adding another dependency.)
