Subject: [PATCH] fix: support pytest on python 3.12 wrt Fraction formatting
 change

python 3.12 supports float-style formatting for Fraction by
https://github.com/python/cpython/pull/100161 .
With this change, when ":n" format specifier is used in format() for
Fraction type, this now raises ValueError instead of previous
TypeError.

To make pytest succeed with python 3.12, make
pint.testing.assert_allclose also rescue ValueError .

Fixes #1818 .
