Replace numbers.Real with Real in numbers.rst

I believe that since we're in the numbers module docs, we can assume that Real means numbers.Real, and Complex means numbers.Complex. In other words, you can assume that from numbers import Real, Complex has already happened.

Yes we can assume it, that is precisely why I opened this pull request, since this is the only part of the code snippet which does not make that assumption.

Ah, sorry I misunderstood.

Not sure about this, since it's supposed to be an example of how to use numbers, and the real code it's based on does use numbers.Real, not Real.

The real code does not use if isinstance(a, Rational): but if isinstance(a, numbers.Rational): so the current numbers documentation is not even consistent with the real code:
