Collission shapes (3D) page does not match mesh options in 4.3

[Yora0]

Your Godot version:
4.3

Issue description:
The menu for creating Collision Shapes has been changed in 4.3, now opening a dialog window with two drop down menus instead of the described in the documentation page.

The "Simplified Convex" option is not described in the page.

The page does not provide information on the term "Sibling", and it does not appear to be covered anywhere in the documentation at all.
