### Godot version

4.1.dev (4d5f10fc3a)

### System information

macOS 13.3.0 - Vulkan (Forward+) - integrated Apple M1 Pro - Apple M1 Pro (8 Threads)

### Issue description

Here is the toolbar button for Path 3D <img width="213" alt="Capture d’écran 2023-06-05 à 01 33 46" src="https://github.com/godotengine/godot/assets/66184050/be23b414-43ca-4775-a91e-e12d4581af4f">. As you can see it is missing the secod button from PAth2D ones <img width="243" alt="Capture d’écran 2023-06-05 à 01 33 34" src="https://github.com/godotengine/godot/assets/66184050/aba2435d-bb16-43e9-af18-30b64e38255f">. This is the one about setting up the control nodes. 
However control nodes are actually implemented and accessible by holding `Shift` so it's only missing a button that makes it looks like control node are not a thing on `Path3D`.
