[Bug]: Incorrect type definition of discountId in updateCheckout

[gorshkovaea]

What happened?

I got an error "Type null is not assignable to type string | undefined" when I tried to call
paddle.Checkout.updateCheckout({ discountId: null, items: [{ priceId: 'newPriceId', quantity: 1 }], });.

I expect the type of discountId to be string | null, as docs state

Steps to reproduce

1. Call paddle.Checkout.updateCheckout in .ts file with discountId: null
2. Get a ts error "Type null is not assignable to type string | undefined"

What did you expect to happen?

paddle.Checkout.updateCheckout({ discountId: null, items: [{ priceId: 'newPriceId', quantity: 1 }], }); works well without any errors

How are you integrating?

React, TypeScript
