Godot version: 4.5 stable

Issue description: In the Math->Beziers, Curves and Path->Adding Control Point section, I believe the Control1 calculation should be Control1 = P2 - P3 instead of P3 - P2. Also, the text of the second and third bullets there should probably be reworded as follows:

• Control0 = P1 - P0: Is a vector relative to the first point
• Control1 = p2 - P3 Is a vector relative to the second point
