Bulk Decrement Inventory Items

Notes::

• trackQuantity must be true to allow for decrementing the quantity.
• If you pass restrictInventory: true and the decrementData.decrementBy amount is greater than the current quantity in stock, the request will fail with an INSUFFICIENT_INVENTORY error.
• Pass restrictInventory: false to allow for negative quantities.
• If you pass preorderRequest: true and the item is available for preorder, the item's preorderCounter will increase and the item's quantity will stay the same.
