Missing documentation pages for the SceneEventMessage and SceneEventData types

Steps to reproduce:

1. Open the manual page for NetworkSceneManager. Link for 2.6 manual version - https://docs.unity3d.com/Packages/com.unity.netcode.gameobjects@2.6/api/Unity.Netcode.NetworkSceneManager.html
2. In the first paragraph, observe that there are hyperlinks for SceneEventMessage and SceneEventData types
3. Click on one of the links

Actual results: Documentation page is missing

Expected results: User is redirected to a relevant documentation page

Reproducible with versions: 1.7.1, 2.6.0

Can’t test with versions: 1.0.0, 1.6.0 (NetworkSceneManager did not present links for the affected types)

Tested on (OS): macOS 26.0.1
