Adds support for the Billie payment method for invoices and subscriptions

What’s new

Adds support for passing billie in payment_settings.payment_method_types when creating or updating an Invoice or Subscription with collection_method set to send_invoice.

Impact

If your invoice and subscription integrations use payment_settings.payment_method_types and send_invoice, you can include billie to let customers pay with Billie on the Hosted Invoice page of the customer portal. See Configure payment methods for invoices for enablement guidance in the Dashboard and API. Billie doesn’t support invoices or subscriptions set to charge_automatically.
