Onboarding isn't resumed after restarting Minecraft

If you close the game while the Onboarding screen is open, it isn't shown when you next open the game. This can be frustrating as it removes the chance to easily enable the Narrator or view the available accessibility options.

Steps to reproduce

1. Create a new instance of Minecraft in your launcher
2. Launch that instance
   → The Onboarding screen appears
3. Before pressing any of the buttons, close Minecraft
4. Re-launch the instance
   → The Main Menu appears
