Material Reference Converter provides same naming for each game object

• Steps to reproduce:

1. Create a built-in project
2. Create three 3d cubes in the scene and save scene in the project
3. install URP package via package manager
4. Open Render Pipeline Converter window (Window > Rendering > Render Pipeline Converter)
5. Checkmark Rendering Settings. Press "Scan". Then "Convert"
6. Checkmark Material Reference Converter. Press "Scan"
7. Observe the naming of Material Reference Converter

Actual results: Naming for each 3d cube is the same

Expected results: Naming for each 3d cube is the different. Perhaps Name Scene + GameObject Name be a good result?
