Require PhoneNumber doesn't work on Android

[aharwood9]

Describe the bug
Adding phoneNumber: "required", to additionalFields works on iOS but has no impact on Android.

To Reproduce

1. Follow this guide to setting up AddressSheet - https://docs.stripe.com/elements/address-element/collect-addresses?platform=react-native
2. Boot up an Android device (physical or emulator)
3. Enter an address and leave phone number blank
4. See you the button becomes enabled as soon as you've entered a zip code
5. Tapping the button triggers onSubmit

Expected behavior

Button should be disabled until phone number is entered (as per iOS) when phoneNumber is required
