Creating a refund allows setting of unknown parameter "currency"

[markjerz]

Describe the bug

RefundCreateOptions has a Currency property in it but that parameter isn't present in the API docs. So, if I set it to something in the code I get an error response back from Stripe about an unknown parameter.

To Reproduce

var refund = await refundService.CreateAsync(
    new RefundCreateOptions {
        PamentIntent = payment.PaymentIntentId.Id, 
        Amount = X,
        Currency      = "gbp"
    });

Expected behavior

I suppose, the Currency property shouldn't exist in the RefundCreateOptions? Or maybe be marked as [Obsolete] if it once was possible (so as not to break existing implementations)?

@markjerz Sorry for the confusion. The currency parameter is only allowed in specific cases and shouldn't be in the library today. We'll look into a fix!
