SRP Batcher incompatibility reason shows a dangling empty "()" when the reason has no variable-specific detail

Steps to reproduce:

1. Create a new URP 3D project via Unity Hub
2. Import the attached Shader
3. Select that shader in the Project window so it opens in the Inspector
4. In the Shader Inspector, read the "SRP Batcher" row (it says "not compatible") and the Info HelpBox shown
      directly below it.

Actual results: The SRP Batcher compatibility HelpBox text ends with a dangling empty pair of parentheses:
   "Material contains grab pass ()"
The trailing " ()" is always present even though the "grab pass" reason has no variable-specific detail to put
inside it.

Expected results: No trailing empty parentheses. The reason should read "Material contains grab pass". The "(<detail>)" suffix
should only be appended when there is an actual variable-specific detail to show.
