Update kinematic_character_2d.rst

Latest godot doesn't need set_physics_process(true), it is enabled by default if it finds the callback.

Also the method move has been renamed to move_and_slide or move_and_collide which makes half the tutorial useless.

 Note that not only the motion has been modified but also the velocity.
 This makes sense as it helps keep the new direction too.
