python 3.12 supports float-style formatting for Fraction by python/cpython#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 .
