rigidbody2d bounce c# example incorrect method

[prashantham]

Your Godot version:
4.0.3

Issue description:
The collision bounce method uses
_velocity = _velocity.Bounce(collisionInfo.Normal);

But there is no Normal field, but a GetNormal() method;
Hence example should have been
_velocity = _velocity.Bounce(collisionInfo.GetNormal());

This example is outdated, it used to be a property in 3.x. In 4.x the example should indeed be using the GetNormal() method.

For context the GDScript's version of this example was updated by #7288.
Pull requests to update it in C# are welcomed 🙂.
