Missing `amazon_pay` in `CreateInvoicePaymentSettingsPaymentMethodTypes` and `InvoicesPaymentSettingsPaymentMethodTypes`

[TmLev]

Describe the bug

Webhook can't deserialize an invoice.paid event due to the CreateInvoicePaymentSettingsPaymentMethodTypes and InvoicesPaymentSettingsPaymentMethodTypes enums missing an amazon_pay variant.

Error:

Error("unknown variant `amazon_pay`, expected one of `ach_credit_transfer`, `ach_debit`, `acss_debit`, `au_becs_debit`, `bacs_debit`, `bancontact`, `boleto`, `card`, `cashapp`, `customer_balance`, `eps`, `fpx`, `giropay`, `grabpay`, `ideal`, `konbini`, `link`, `p24`, `paynow`, `paypal`, `promptpay`, `sepa_credit_transfer`, `sepa_debit`, `sofort`, `us_bank_account`, `wechat_pay`", line: 260, column: 2)

To Reproduce

1. Receive an invoice.paid event with the following payment_method_types:

   "payment_method_types": [
     "acss_debit",
     "amazon_pay",
     "cashapp",
     "link",
     "us_bank_account",
     "card"
    ]

2. Try to deserialize it:

   let raw = serde_json::json!("amazon_pay").to_string();
   let payment_method_type: CreateInvoicePaymentSettingsPaymentMethodTypes =
       serde_json::from_str(&raw).unwrap();
   println!("{:?}", payment_method_type);

3. Error:

   Error("unknown variant `amazon_pay`, expected one of `ach_credit_transfer`, `ach_debit`, `acss_debit`, `au_becs_debit`, `bacs_debit`, `bancontact`, `boleto`, `card`, `cashapp`, `customer_balance`, `eps`, `fpx`, `giropay`, `grabpay`, `ideal`, `konbini`, `link`, `p24`, `paynow`, `paypal`, `promptpay`, `sepa_credit_transfer`, `sepa_debit`, `sofort`, `us_bank_account`, `wechat_pay`", line: 1, column: 12
   

Expected behavior

CreateInvoicePaymentSettingsPaymentMethodTypes and InvoicesPaymentSettingsPaymentMethodTypes should deserialize amazon_pay
