🚑 Clarify patch condition for doctest finder hack (pytest-dev#12471)

There was a regression caused by pytest-dev#12431 that excluded the patch on
broken CPython patch version ranges 3.11.0–3.11.8 and 3.12.0–3.12.2.

This change fixes that by adjusting the patching conditional clause
to include said versions.

Closes pytest-dev#12430.
