 Ensure system tray is created when the event loop is ready. Menu item modifications are not applied unless it is ready.
-If you need to modify the menu items immediately after creating a tray in the setup hook,
-either directly configure the menu item change when creating the menu or move the code when `RunEvent::Ready` is fired.
-See https://docs.rs/tauri/latest/tauri/struct.App.html#method.run for more information.
