Quick order list: Change 'plural' string to 'singular' when removing '1 item' on 'Remove all' confirmation

[edmund-teh]

When a buyer is using the Quick order list and clicking Remove all with only 1 item in cart, the confirmation messaging should say, Remove 1 item from cart? instead of Remove all 1 items from your cart?.

This may need further assistance with translations too.

@melissaperreault's screenshot of the old string here: https://screenshot.click/08-53-yegxl-npeta.png

Steps to reproduce:

1. When interacting with the Quick Order list section and you've added 1 item to cart, Total items = 1
2. Click 🗑️ Remove all
3. The confirmation messaging says Remove all 1 items from your cart?, which is wrong
4. For this singular case only, it should read Remove 1 item from cart?
5. For all other cases, it should read Remove all # items from your cart?
