showPriceConsentIfNeeded method
Shows the price consent sheet if the user has not yet responded to a subscription price change.
Use this function when you have registered a SKPaymentQueueDelegateWrapper
(using the setDelegate method) and returned false when the
SKPaymentQueueDelegateWrapper.shouldShowPriceConsent() method was called.
See documentation of StoreKit's -[SKPaymentQueue showPriceConsentIfNeeded].
