Bows use an outdated pallet

Bows use an outdated 'string' pallet when compared to crossbows, fishing rods, etc.. The colors on the 'arrow rest' are also outdated when compared to the 'arrow rest' on crossbows.

Fletching tables show bows with the correct updated string pallet on one of their sides, so this is most definitely a bug. Bows were never updated in the texture update.
