Skeleton3D: setting animate_physical_bones in the Inspector does not work

Issue description

After using "create physical skeleton" and playing an animation during runtime, the physical bones won't animate despite animate_physical_bones being set to true in the inspector.

Setting it to true through code in _ready makes the bones animate correctly.

Steps to reproduce

• Import a rigged 3D model with an animation
• In the 3D viewport, use Skeleton -> create physical skeleton
• Optional: adjust the physical bones so that they're more visible
• Enable visible collision shapes in the debug tab
• place the model in a scene with a camera and see the bones remaining in the default pose while the mesh is animated
• Enable the option through code and see that it works correctly

func _ready():
	skeleton.animate_physical_bones = true

Minimal reproduction project

See #75894 for an MRP that can be used to test this

Thanks for splitting this bug off into a seperate issue :D

I want to also add that calling physical_bones_start_simulation(["some_bone"]) makes all the bones except "some_bone" stop being animated.

skeleton.AnimatePhysicalBones = true; // Work around for current issue
skeleton.PhysicalBonesStartSimulation(new() { "spine.005" });
// All the physical bones stopped being animated =(
