Virtual account creation instructions for payment requests

Currently, when Virtual Accounts are enabled in a client’s configuration, Payment Requests automatically have Virtual Accounts created by default.

However, as some clients have indicated they require more control over when Virtual Account BSB/account numbers are created, Azupay have introduced a new field enableVirtualAccount to specify that a payment request should have a Virtual Account number created for it, rather than applying this behaviour universally to all new payment requests.

For more information on this new feature, pelase refer to the Payment Request API file spec here: https://developer.azupay.com.au/reference/createpayidpaymentrequest#/
