[3.12] gh-119189: Fix the power operator for Fraction (GH-119242) (GH-119835)

Browse source 
When using the ** operator or pow() with Fraction as the base
and an exponent that is not rational, a float, or a complex, the
fraction is no longer converted to a float.
(cherry picked from commit b9965ef282)
