[docs] State Management reference using GlobalWindowEvent

Docs reference using GlobalWindowEvent

use tauri::{Builder, GlobalWindowEvent, Manager};

....

// In an event handler:
fn on_window_event(event: GlobalWindowEvent) {
    // Get a handle to the app so we can get the global state.
    let app_handle = event.window().app_handle();
    let state = app_handle.state::<Mutex<AppState>>();

    // Lock the mutex to mutably access the state.
    let mut state = state.lock().unwrap();
    state.counter += 1;
}

But, as far as I can see, GlobalWindowEvent on v2 does not exist, instead we have WindowEvent, which does not give you access to the underlying window()?
