Documentation error in Button::selectable()

[MetaflameDragon]

This is a simple error in the documentation for Button::selectable().

The documentation states that the code is equivalent to:

let selected = true;
ui.add(Button::new("toggle me").selected(selected).frame_when_inactive(!selected).frame(true));

However, the source code itself refutes this:

pub fn selectable(selected: bool, atoms: impl IntoAtoms<'a>) -> Self {
    Self::new(atoms)
        .selected(selected)
        .frame_when_inactive(selected) // <- not negated!
        .frame(true)
}

It's a super minor thing, but it just really surprised me when I first tried writing out the equivalent code in full, and the selectable buttons looked unexpectedly wrong.
