Add confirmCardPayment option for PaymentIntents API

[jordanchitty]

I have added a confirmCardPayment method to reflect the changes to the Stripe JS API. ConfirmCardPayment replaces CompletePaymentIntent, which has been deprecated. ConfirmCardPayment allows Stripe JS to handle SCA authentication correctly in the modal. https://stripe.com/docs/js/payment_intents/confirm_card_payment

I used confirmPaymentIntent method instead

 this.stripe
          .confirmPaymentIntent(this.secretToken, this.element, {
            payment_method_data: {
              billing_details: {
                 address: {
                   city: 'Irving',
                   country: 'CA',
                   line1: '123 A Place',
                   line2: 'Suite 100',
                   postal_code: 'VOE 1H0',
                   state: 'BC'
                 },
                email: '',
                name: '',
                phone: '';
              }
            }
          })
