In a customFlow payment flow, the selected payment option image is always blank or a placeholder

[mgouault]

Describe the bug On iOS and Android, starting from 0.36.0, in a payment flow with customFlow: true, the return payload of presentPaymentSheet().paymentOption.image is either a placeholder or a blank image instead of being the corresponding card's brand's icon.

To Reproduce

1. To make it easier to identify the issue I have created a repository from my reproducible example : https://github.com/mgouault/expo-test-stripe, it just needs a publishableKey and a paymentIntentClientSecret to work.
2. Otherwise, steps to reproduce the behavior:
3. Start from a boilerplate of "create-expo-app" in bare workflow with "@stripe/[email protected]"
4. Build and run on iOS
5. Setup a two-step payment flow (aka customFlow) using <StripeProvider>, useStripe(), initPaymentSheet(), and presentPaymentSheet().
6. Call initPaymentSheet with customFlow: true then use presentPaymentSheet()
7. The payment sheet opens, add a simple Visa test card (4242 4242 4242 4242 03/99 999), then tap "Continue"
8. The return of presentPaymentSheet() contains "paymentOption" but "paymentOption.image" is a placeholder instead of being the Visa icon
9. On Android the image is not a placeholder but a blank rectangle (instead of being the Visa icon).

Expected behavior The return payload of presentPaymentSheet() "paymentOption.image" should be a base64 image of the corresponding card brand icon.
