[TN-267] Automatically open keyboard upon reaching PIN step for RN SDK

[ccrawford4]

Scenario: User enters phone number and clicks 'Send SMS'. User is sent to next screen. Currently, keyboard does NOT automatically open.

Instead, keyboard should be open and PIN input field in focus, so user can start typing the pin OR select the automatic iOS suggestion (the one above the keyboard pulled from iMessage) without any other clicks necessary.

@oottoohh :

our otp side is webview, so we cant handle behaviour of keyboard. i already try to inject script input inside webview to trigger number pad but it fail.
