Remove the resetGame() method

[stringdotjar]

Description

This PR removes the resetGame() method from the framework, as we (like many others) have to fight libGDX to properly restart the game.

We might possibly add this back in the future, but as of right now, we won't support it, as based on how libGDX is designed, there's no easy nor efficient way to properly execute this kind of functionality without hacky workarounds and potentially breaking the framework.
