Animation Parameters example code uses legacy Input System causing “InvalidOperationException” errors spam in the Console window

Steps to reproduce:
1. Create new Unity project
2. Create a Cube GO in Hierarchy window
3. Import provided script “NewMonoBehaviourScript.cs” to the project
4. Attach the script to Cube
5. Enter Play mode
6. Observe the Console window

Actual results: Errors “InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.” are spammed in the Console window, using code from documentation page is outdated - https://docs.unity3d.com/6000.4/Documentation/Manual/AnimationParameters.html

Expected results: No errors should be thrown in the Console, documentation should be updated to use new Input System

Reproducible with versions: 6000.0.65f1, 6000.3.4f1, 6000.4.0b4, 6000.5.0a4

Tested on (OS): macOS Silicon Tahoe 26.2 (M1)
