Adds a gamerule that allows you to change the air drag related to the level of speed and slowness you have. By default, the gamerules control the amount that gets added or removed from the air drag modifier attribute per effect level
For example: A player with Speed 2 will have 0.50 less on the Air Drag Modifier attribute, making them slightly more floaty and making it faster to move around in the air while jumping
Gamerule options:
slowness_air_drag_per_level: Default 0.50, Gets added to the Air Drag Modifier attribute, making it slower to move while in the air with the slowness potion effect.
speed_air_drag_per_level: Default 0.25, Gets removed from the Air Drag Modifier attribute, making you faster while sprint jumping when you have the speed potion effect
