Kinematic player can go through walls

[DerekCresswell]

Look into and fix that the current kinematic player can move through the walls.

Perhaps the player needs to be dynamic and use Rigidbody.MovePosition

I don't think we can feasibly make this work for the simplicity we need.
Make the player dynamic, 0 gravity, and frozen Z rotation. Can be a little wacky but gotta keep it simple.

What needs doing :

• Update PlayerInput.md to use the new movement system outlined in the PlayerMovement.cs file.
• Update Prefabs.md to correctly setup the player prefab as above.
