Subtle error in `getattr_hook` example in the Descriptor Guide

Documentation

The example below, from the Descriptor Guide, does not seem to reflect the behaviour of the actual implementation.

https://github.com/python/cpython/blob/ced2691de4c9500ac9a5ccded00741a5fc2d9d2c/Doc/howto/descriptor.rst?plain=1#L733-L740

Unless I'm mistaken, line 736 return obj.__getattribute__(name) should actually read return type(obj).__getattribute__(obj, name).

It's easy to miss when thinking of class instances, but the issue becomes more evident when the example is applied to an attribute lookup on a class object instead. The example would call the __getattribute__ method of the class itself, while the actual implementation calls __getattribute__ on the metaclass (not to mention that in this case the call in the example would fail, due to a missing argument, as it is calling a plain function, rather than a bound method).

Abre Doc/howto/descriptor.rst alrededor de las líneas 733-740 y compara el ejemplo de getattr_hook con el comportamiento de la implementación descrito en el issue, especialmente para la búsqueda de atributos de objetos de clase. Si se confirma la discrepancia, actualiza la expresión de retorno documentada y verifica que la guía coincida con la implementación.
