Shader warnings thrown when applying changes in Shader Build Settings > Keyword Declaration Overrides

Steps to reproduce:
1. Create new Unity project using empty Universal 3D Template
2. Open Project Settings window
3. Select Graphics tab
4. Press “+” button to add a new keyword in Keyword Declaration Overrides
5. Type a keyword name (Testing would do)
6. Change “Type override” to “shader_feature”
7. Press “Apply” button
8. Observe the Console window

Actual results: Shader warnings are thrown in the Console when applying Keyword changes in Keyword Declaration Overrides
Expected results: No Shader warnings are thrown when applying

Reproducible with versions: 6000.3.0b3, 6000.4.0a1
Can’t test with versions: 6000.2.6f1 and lower (No Shader Built Settings available)

Tested on (OS): Windows 11, macOS Silicon, Sequoia 15.6 (M1)
