Inspector: Help tooltips display section titles from several words without the spaces

Steps to reproduce:

1. Create a 2D project
2. Add any 2D game object for example "Capsule"
3. Select the added game object and verify that its data is displayed in the "Inspector" tab
4. Hover the help icons in the "Mesh Renderer" section or "Box Collider" or any other from several words.

Expected result: Tooltip should present the section title with the space as it is displayed in the "Inspector". It should be "Open Reference for Mesh Renderer".

Actual result:  Now it looks like this "Open Reference for MeshRenderer". Added screenshot in the "Attachments" section.

Reproducible with: 2021.3.27f1, 2022.3.1f1, 2023.1.0b20, 2023.2.0a18.
