Documentation link on "Migrate to URP" opens the Unity 6.6 manual from a Unity 6.7 editor

Summary:

The documentation link on the Project Auditor Migrate to URP page resolves to the Unity 6000.6 manual when opened from a Unity 6000.7 editor, so users following migration guidance from a 6.7 project are shown the previous version's instructions even though the matching 6.7 page exists.

Steps to reproduce:

1. Open a URP project in 6000.7.0a6.
2. Open Window > Analysis > Project Auditor and run an analysis.
3. Select the Migrate to URP page.
4. Open the page's documentation link.
5. Look at the URL and at the version selector in the top-left of the docs page.

Actual results: Browser lands on

docs.unity3d.com/6000.6/Documentation/Manual/urp/upgrade-guides.html 

with the docs version selector showing 6.6 (6000.6), while the editor title bar reads Unity 6.7 Alpha (6000.7.0a6)

Expected results: The 6.7 manual, i.e. docs.unity3d.com/6000.7/Documentation/Manual/urp/upgrade-guides.html.

Reproducible with version: 6000.7.0a6

Tested on (OS): MacBook Pro - Tahoe 26.6.2
