Adds support for card installments on Confirmation Token

What’s new

Confirmation Token objects created by the Payment Element contain payment_method_options.card.installments if the cardholder selected an installment plan.

In addition, when you create a test Confirmation Token you can also supply an installment plan in payment_method_options.card.installments.plan.

Impact

This change coincides with the release of card installments support on the Payment Element and adds visibility into cardholder choices.
