`ItemMoveListener` causing a lot of lag due to `isShopBlock` creating chest snapshots

What is happening?

ChestShop is using a LOT of CPU time due to the snapshots created for the isShopBlock checks. While ChestShop does take care to not create snapshots on the ItemMoveListener for the source/destination blocks, ChestShop still checks chests with snapshots, which causes the TPS to tank hard if you have multiple hoppers.

Currently the isShopBlock implementation is like this...

    public static boolean isShopBlock(InventoryHolder holder) {
        if (holder instanceof DoubleChest) {
            return isShopBlock(((DoubleChest) holder).getLeftSide())
                    || isShopBlock(((DoubleChest) holder).getRightSide());
        } else if (holder instanceof BlockState) {
            return isShopBlock(((BlockState) holder).getBlock());
        }
        return false;
    }

But it could be like this, considering that it seems that ChestShop doesn't need the block states to be a snapshot.

    public static boolean isShopBlock(InventoryHolder holder) {
        if (holder instanceof DoubleChest) {
            return isShopBlock(ImplementationAdapter.getLeftSide((DoubleChest) holder, false))
                    || isShopBlock(ImplementationAdapter.getRightSide((DoubleChest) holder, false));
        } else if (holder instanceof BlockState) {
            return isShopBlock(((BlockState) holder).getBlock());
        }
        return false;
    }

Currently as a workaround I'm using TURN_OFF_HOPPER_PROTECTION to true, that "fixes" the issue.

Additional context

Yes, in reality I'm not running the latest version (it is a few builds behind), but I have checked the code and there wasn't any changes on that code path between the version I'm using and the latest version.

And yes, I'm using a Paper fork that I made, but by looking at the code I can see that the same behavior would also happen in Paper.
