Empty "Publishing Settings" foldout is shown under Standalone Player Settings and collapses other foldouts when expanded

Steps to reproduce:

1. Create a new 3D URP project
2. Go to Edit > Project Settings
3. Select Player settings
4. Observe the foldouts under "Settings for Windows, Mac, Linux"

Actual results: An empty "Publishing Settings" foldout is shown. Expanding it reveals no properties or information. Additionally, expanding the "Publishing Settings" foldout collapses any other previously expanded foldouts (e.g. Icon, Resolution and Presentation, Splash Image)

Expected results: The empty "Publishing Settings" foldout should not be present on Linux for the Standalone target - consistent with macOS and Windows, where it is not shown (or it should contain the relevant properties if any exist)

Reproducible with versions: 6000.5.0a9 (253a859729df), 6000.5.0b11, 6000.6.0a6

Not reproducible with versions: 6000.4.10f1, 6000.5.0a8
