[issue44547] fraction.Fraction does not implement __int__.

[Michael Amrhein]

New submission from Michael Amrhein <michael at adrhinum.de>:

While int, float, complex and Decimal implement __int__, Fraction does not. Thus, checking for typing.SupportsInt for fractions fails, although int(<fraction>) succeeds, because Fraction implements __trunc__.
This looks inconsistent.
Easiest fix seems to be: Fraction.__int__ = Fraction.__trunc__
