Update to Godot 4

With the Godot 4 Testing Phase out the way and My experience with it increasing, Version 2 of the Demo will be making the Leap to Godot 4 and I'm Hoping to get the Updated Version Done Soonish.

Updated Features:

New Assest Pack
Intro
Tutorial Level (Aka the only level in the game as of now)
Hub World
Music Changed
Lighting Fixes
More may be added but just gotta wait for Demo Release 2.0
