Skeleton2D broken

### Tested versions

godot 4.2.1, macOS 14.3.1 on macbook pro M2 max

Edit: tested also with 4.2, and that seems to work

### System information

macOS 14.3.1 on macbook pro M2 max, forward and mobile renderer tested

### Issue description

Trying to go though the [tutorial ](https://docs.godotengine.org/en/stable/tutorials/animation/2d_skeletons.html)in the docs, I had issues. I already made an issue for the documentation (it still needs a few correction, allthough it is not as bad as I thought) here: https://github.com/godotengine/godot-docs/issues/9150

The bug is related to rotation of the bones. Both the bones themselves and the polygons/images are not rotated correctly. In godot 3 this works as expected.

### Steps to reproduce

- Simply follow the tutorial with v4.2.1
- Observe issues with rotation.

### Minimal reproduction project (MRP)
