Corrected the C# code from the example in the 'Controlling the animation' section, fixing the class name used by the generic method GetNode<T>(), as well as the string parameter.
* update animation tree iamges
these animation trees used the "KinematicBody2D" node which has been
replaced in Godot4 with the CharacterBody2D node. These images have been
updated accordingly
* Added images for AnimatedSprite from spritesheet
Added images to show how to use the AnimatedSprite class with a spritesheet in the tutorial.
* Using AnimatedSprite with a sprite sheet
I updated this tutorial to show how to easily use a sprite sheet with the AnimatedSprite class, including some screen shots. I changed the old wording that makes it sound like you cannot use a sprite sheet with AnimatedSprite. I also changed the wording that makes it sound as if you must choose between using the AnimatedSprite class or the AnimationPlayer, as you can use an AnimationPlayer with an AnimatedSprite.
* Changed wording on proposed update
I changed the wording to remove "easily" and verbs ending in "ing" to meet the doc's writing guidelines.
