firebase-ios-sdk: Auto Logging In-App Purchases not working with StoreKit 2

Description

I am submitting this issue to report that StoreKit 2 in-app events are not being automatically logged. While I have not experienced any issues with the automatic logging until the last app update, I have noticed that in-app purchases are not showing up in the logs. This is particularly strange as in-app purchases have always been tracked automatically in my app. No changes have been made to the Firebase implementation of the app either. In fact, other automatic events such as first_open and session_start are still being logged successfully.

The only change that was implemented is the transition to using the StoreKit 2 implementation of in-app purchases. Instead of using the SKPaymentQueue, I am now calling the .purchase() method on a Product object (https://developer.apple.com/documentation/storekit/product/3791971-purchase).

Reproducing the issue

This issue can only be reproduced when making a purchase using the StoreKit 2 implementation.
