Fix minor typo in #ifdef docuementation

As reported in https://gcc.gnu.org/pipermail/gcc/2025-July/246417.html,
This fixes the minor typo under the #ifdef documentation about adding
MACRO after the #endif and the MACRO matching of the #ifdef. It had `#ifndef`
in it, rather than `#ifdef`.

Pushed as obvious.

gcc/ChangeLog:

	* doc/cpp.texi (#ifdef): Correct typo.

 Sometimes you wish to use some code if a macro is @emph{not} defined.
