Support for upcoming changes to Stripe Prefilling saved cards in Checkout

[mrpritchett]

On May 1, 2024, Stripe is changing how cards saved during checkout are going to be made available during checkout for future purchases. It looks like a few new checkout session options are going to be made available to ensure compatibility with current systems.

Is there any way we can get support these things in Cashier? I apologize is this isn't the right forum for this kind of request. Spent about 15 minutes trying to decide which "bucket" it belonged in.

Thanks for proposing this! I think we can do something here yeah. I'm seeing this as a new HandlesPaymentMethods concern trait which can be placed on the CheckoutBuilder, SubscriptionBuilder and PerformsCharges trait. This can then keep two properties, one for https://docs.stripe.com/api/checkout/sessions/create#create_checkout_session-saved_payment_method_options-allow_redisplay_filters and one for https://docs.stripe.com/api/checkout/sessions/create#create_checkout_session-saved_payment_method_options-payment_method_save

Then, these could be set by different methods like allowSavingPaymentMethod, disableSavingPaymentMethod, alwaysRedisplayPaymentMethod, limitRedisplayPaymentMethod, etc.

Lastly, these can then be wired up through the __construct of the CheckoutBuilder.

Would love a PR for this!
