Consider the following QML code:

import QtQuick
import QtQuick.Controls

Item {
    Button {
        text: "Foo"
        onClicked: console.warn("Hello")
        action: Action {
            shortcut: "Ctrl+L"
        }
    }
} 

The button has a shortcut assigned to it. This shortcut should be exposed to the accessibility tree so that screenreaders can announce it.

QAccessibleActionInterface has keyBindingsForAction, but that doesn't seem to be implemented in QAccessibleQuickItem at all
