To Reproduce
Steps to reproduce the behavior:

1. Open the payment sheet
2. Turn on the talkback from the device settings.
3. Tap on the Checkout CTA
4. Listen to the VO of the different elements on the screen
5. Enter a cc decline card (4000000000000002) and try to submit. Listen to the VO

Expected behavior

1. After double tapping on checkout, the focus and VO should be moved to the Payment sheet, not on the background screen.
2. The VO for the Pin/Zip code field data should be announced in single separated digits (9 8 1 0 1) not in words (ninety-eight thousand one hundred one).
3. The inline error message should be focused and announced asap when a user enters an invalid card number or expiry date.
4. When the user navigates back to the card number or expiration date field with the left swipe gesture, the VO of the inline error message should be announced exactly as it is displayed along with the value that is “Edit box: 424242… Card number. Your card number is invalid“ not the “Edit box: 424242…Card number. Error: Invalid input“.
5. The trait (Button, Double-ta to activate) should be announced for the VO of “Pay“ CTA.
6. The focus should move to the error message after double tapping on Pay CTA. (for all the error states like, expiry card, Incorrect CVC, card_declined_on_card_add).
