Get the list of bones that we configured to be included during training. A bone reference is basically just a name of a bone. This can be different from the bone list inside the InputInfo property though. Please keep in mind that the BoneIncludeList is what is setup in the UI, but the InputInfo contains the actual list of what we trained on, so what we use during inference. A user could change this bone list after they trained a model, in which case the input info and this bone include list will contain different items.
