Localization: Help ("?") button on the Locale asset Inspector leads to a missing Unity Manual page

Steps to reproduce:

1. Create a new project with 6000.6.0f1
2. Install the Localization package (com.unity.localization)
3. Open Edit > Project Settings > Localization and create the Localization Settings asset
4. Click Add Locale, tick a locale - for example Lithuanian - and confirm with Add Locales
5. Select the created Lithuanian (lt) Locale asset in the Project window
6. In the Inspector, click the help ("?") button on the "Lithuanian (lt) (Locale)" header
7. Observe the page that opens in the browser

Actual results: The browser opens docs.unity3d.com/6000.6/Documentation/Manual/class-Locale.html and the Unity Documentation site returns "Sorry... that page seems to be missing!". The related-pages and search-results blocks are empty, so no alternative is offered

Expected results: The help button opens the documentation page for the Locale asset

Reproducible with versions: 6000.5.7f1, 6000.6.0f1, 6000.7.0a6

Tested on (OS): MacBook Pro - Tahoe 26.6.2
