Doc: Improve code snippet in QTranslator overview 

Use translator::load(QLocale(), ...) which loads the a translation mapping
the users preferred languages, instead of just hardcoding one. This is
arguably the more common (and interesting) case.

Also, QPushButton::tr() does place the string in the "QPushButton"
namespace, which is just wrong (TM).
