doc: remove a note about functor-based connection complexity for overloads
What we had initially:
connect(slider, &QSlider::valueChanged,
lcd, static_cast<void (QLCDNumber::*)(int)>(&QLCDNumber::display));
was more complex than string-based solution:
connect(slider, SIGNAL(valueChanged(int)),
lcd, SLOT(display(int)));
But since Qt 5.7 we have qOverload/QOverload:
connect(slider, &QSlider::valueChanged,
lcd, QOverload<int>::of(&QLCDNumber::display));
connect(slider, &QSlider::valueChanged,
lcd, qOverload<int>(&QLCDNumber::display));
Which is not complex at all, just a bit different to what Qt developers
are used to.
