How to reproduce:
1. Create a new Unity project
2. Go to Window -> Package Management -> Package Manager -> Unity Registry -> Features -> ECS -> QuickStart
3. Observe the opened page

Expected results: The opened page is a Unity Documentation page (https://docs.unity3d.com/6000.4/Documentation/Manual/ECSFeature.html)
Actual results: The opened page is a DOTS overview page (https://unity.com/dots)

Reproducible with: 6000.2.0a5, 6000.2.14f1, 6000.4.0a2, 6000.4.0b3, 6000.5.0a3
Not reproducible with: 6000.1.17f1
Can't test with: 6000.0.65f1, 6000.2.0a4 (No ECS Feature Set)

Reproducible on: macOS Tahoe 26
Not reproducible on: No other environment tested

Note: Not a regression because the right documentation was never used in the 6.2 stream
