Diagnostics Data Label Uses Incorrect Bold Styling in Build Profile Detail View

Steps to reproduce:

1. Create a new Unity project
2. Ensure Diagnostics is enabled via Project > Services > Diagnostics
3. Open the Build Profile window
4. Select one of the following platforms: (macOS, Windows, Dedicated Servers, Android etc.)
5. In the detail view, observe the Diagnostics section

Actual results: The Diagnostics Data label is styled in bold, making it visually identical to the "Diagnostics" section header

Expected results: The Diagnostics Data label should use regular (non-bold) styling to visually distinguish it from the section header
