"Metal: Vertex shader missing buffer binding at index 2 (UnityPerDraw)" warnings are spammed in Console when Built-in target is added to Shader Graph in URP project

Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. Import provided “New Shader Graph.shadergraph” Asset to the project

5. Open Shader Graph
6. In Active Targets add Built-in target
7. Save changes and open Scene view
8. Observe the Console window

Actual results: Actual: “Metal: Vertex shader missing buffer binding at index 2 (UnityPerDraw / Shader Graphs/New Shader Graph)” warnings are spammed in the Console window

Expected results: No warnings are spammed in the Console window
