Warning icon for the "Asset Import Overrides" has low visibility in Light Unity theme

Steps to reproduce:

1. Create a new project 
2. Unity theme should be set to "Light" (Unity > Settings > General > Editor Theme > Light)
3. Open the Build Profiles window (File > Build Profiles)
4. Click the "Add Build Profile" button
5. Select the Windows or macOS platform and click the "Add Build Profile" button
6. Click the "Asset Import Overrides", located in the top-right corner
7. Select any value from the "Max Texture Size" dropdown list and click "Apply Overrides"
8. Observe the result

Actual results: A poorly visible warning icon appears in front of the "Asset Import Overrides" string

Expected results: The icon that appears should be brighter. It should be adapted to the "Light" Editor theme.
