Avoid using Time.fixedDeltaTime with Update

Rule ND3203 API Usage / Unity

Update() and FixedUpdate() depend on the frame rate. Use Time.deltaTime instead of Time.fixedDeltaTime: it automatically returns the right delta time inside these functions.

How to fix

Replace Time.fixedDeltaTime with Time.deltaTime within Update() and FixedUpdate().
