2D Skeletons tutorial seems outdated. Doesn't mention skeleton 2D node that's apparently needed.

Godot Version 4.0.2.stable.mono

When following the tutorial, there's a part where bones are made in the arm. When following along in Godot, the bones aren't generated the same way, and have errors indicating that they need a Skeleton2D or another bone node parent. I'm fresh to the system, and don't know what to do from here at all.

Everything in the Skeletons section is outdated and incorrect, from the lack of a Skeleton2D node at the root, to menu options that no longer exist, which includes using the old method of generating IK constraints. As a result, there actually isn't any documentation/tutorialisation on actually implementing any IK constraints as they exist right now.
