Replace instances of KinematicBody with CharacteBody in READMEs

KinematicBody was replaced by CharacterBody in Godot 4.0.

This also adds the 3D suffix to 3D physics classes.

 Example of how to make a kinematic character controller in 2D using
-[`KinematicBody2D`](https://docs.godotengine.org/en/latest/classes/class_kinematicbody2d.html).
+[`CharacterBody2D`](https://docs.godotengine.org/en/latest/classes/class_characterbody2d.html).
 The character moves around, is affected by moving platforms,
 can jump through one-way collision platforms, etc.

 Custom node types are added in a Godot plugin to allow 2.5D objects. Node25D serves as the base for all 2.5D objects. Its first child must be a 3D Spatial, which is used to calculate its position. Then, add a 2D Sprite (or similar) to display the object.

 Several view modes are implemented, including top down, front side, 45 degree, isometric, and two oblique modes. To implement a different view angle, all you need to do is create a new set of basis vectors in Node25D, use it on all instances, and of course create sprites to display that object in 2D.
