Some proration mode is not working when upgrading and downgrading

Description

Hi,

First of all, thank you very much for providing this good library so we can work with In-app-purchase for both Android/Apple conveniently.

I am writing because I have some issue while selecting a proration mode to upgrade / downgrade subscription using base plan.

I have set up 3 base plans.

I have tried to use proration mode DEFERRED for downgrading subscription, however, Android is giving me an error.
Also, I am getting the same error when I am using IMMEDIATE_AND_CHARGE_PRORATED_PRICE for upgrading.
However, other proration modes work.

Is this happening because BillingFlowParams.ProrationMode is deprecated?

Would it work if react-native-iap uses BillingFlowParams.SubscriptionUpdateParams.ReplacementMode instead?

Expected Behavior

Show Android upgrade/downgrade modal with subscription details.

Screenshots

Environment:

• react-native-iap: 12.10.7
• react-native: 0.71.1
• Platforms (iOS, Android, emulator, simulator, device): emulator, Android device (Samsung S22)

To Reproduce
Steps to reproduce the behavior:

1. Use ProrationModesAndroid.DEFERRED when downgrading

2. Use ProrationModesAndroid.IMMEDIATE_AND_CHARGE_PRORATED_PRICE when upgrading

3. Error below is shown,

 WARN  {"code": "E_DEVELOPER_ERROR", "debugMessage": "Requested replacement mode is not supported for this request", "message": "Google is indicating that we have some issue connecting to payment.", "responseCode": 5}
 LOG  Error requesting subscription:  [Error: Google is indicating that we have some issue connecting to payment.]

Thanks.
