Current behavior

Firebase documentation states the following on tracking in app purchases with storekit 2

However the logTransaction() is not available in capacitor-firebase and logging the event using
FirebaseAnalytics.logEvent({name: 'in_app_purchase', params: {productIdentifier: productIdentifier}});

gives the following log message: 10.24.0 - [FirebaseAnalytics][I-ACS013006] Event name is reserved. Ignoring event: in_app_purchase

Expected behavior

I would expect to be able to log an iOS StoreKit 2 purchase. This is now not possible because google analytics expects the key_event name to be in_app_purchase which is reserved..

@robingenz with storekit 1 officially being deprecated it would be awesome to somehow support the logging of storekit 2 purchases
