2. since we have item quantity, we need to update the ItemButton to show the quantity when it's greater than 1, and to show the price only inside the shop, also the inventory should loop over all items searching for a similar item that it's quantity is smaller than it's maximum quantity then it increases it instead of adding it as a new item. we don't need to loop if the item's maximum quantity is equal 1.
