Fix bug causing ShaderGraph files to open in IDE rather than ShaderGraph editor (the issue was the plug-in that is bundled with Rider)

MaterialGraphProject/Assets/UnityShaderEditor/Editor/Importers/ShaderGraphImporterEditor.cs

 using UnityEditor.ShaderGraph;
 using UnityEditor.ShaderGraph.Drawing;
 using UnityEngine;
-using Debug = System.Diagnostics.Debug;
 using Object = UnityEngine.Object;
 
 [CustomEditor(typeof(ShaderGraphImporter))]
         return true;
     }
 
-    [OnOpenAsset]
+    [OnOpenAsset(0)]
+        Debug.Log(instanceID);
         var path = AssetDatabase.GetAssetPath(instanceID);
         return ShowGraphEditWindow(path);
     }
