"Learn more" link in Project Preview Theme settings opens Unity 6.2 documentation instead of documentation for the Editor stream in use

Steps to reproduce:

1. Create a new project 
2. Open Edit > Project Settings
3. Select the "UI Toolkit" section
4. Scroll to the "Project Preview Theme" group
5. Click the "Learn more" link in the help box

Actual results: The link opens docs.unity3d.com/6000.2/Doc... on every affected stream - the "UI Builder interface overview" page on the Unity 6.2 stream, which displays the banner "This version of Unity is unsupported."

Expected results: The link opens documentation for the Editor stream in use

Reproducible with versions: 6000.5.7f1, 6000.6.0b8, 6000.7.0a5

Can’t test with versions: 6000.0.80f1, 6000.3.22f1 as the Project Preview Theme section is not available in these streams

Tested on (OS): MacBook Pro - Tahoe 26.6.1
