### Godot version

4.0.dev [0f76ff2]

### System information

Kubuntu GNU/Linux 23.04

### Issue description

In the current `master` (stable seems fine), the `EditorSettings` doc is nowhere to be found in the editor, even though it exists: https://github.com/godotengine/godot/blob/master/doc/classes/EditorSettings.xml

### Steps to reproduce

Search for "EditorSettings" in the help dialog, or try clicking in a reference to it.
