Move line item quantity before price in the dom

[spencercanner]

• Rearrange the line item elements so the quantity comes before price in the dom
• This allows merchants using a screen reader to access the total line item price after making updates to the quantity

To 🎩 :

• Verify that the line item styling/layout is not affected by these changes
  • Line item without discounts

• Line item with discounts

• Sanity check other line item configs work as expected:
  • contents > priceWithDiscounts: false, price: true
  • contents > quantity: false, priceWithDiscounts: true
  • contents > quantity: false, price: true
  • order >price, priceWithDiscounts, quantity
