    🦀 Main function, used to:
    - Add Ressources -> Resources are global data we can use later across Systems, independently of entities. Learn more: https://bevy-cheatbook.github.io/programming/res.html
    - Register Systems -> Think Bevy ECS Systems like a database, Systems are a way to "query" our data to implement game logic. Learn more: https://bevy-cheatbook.github.io/programming/systems.html
    - Run our app
