Wrong attribute "invoice_number" is used

[dernst-art]

Hi,

SyliusPayPalPlugin version affected: v1.3.0

Description During creation and updates of PayPal orders and payments there is used the attribute "invoice_number", this attribute got ignored from PayPal.

Possible Solution According to the PayPal API doc the attribute should be named "invoice_id"

• payments: https://developer.paypal.com/docs/api/payments/v2/#captures-refund-request-body
• orders: https://developer.paypal.com/docs/api/orders/v2/#definition-purchase_unit_request

This has to be changed in the following files:

• Sylius\PayPalPlugin\Client\PayPalClientInterface\RefundPaymentApi
• Sylius\PayPalPlugin\Api\CreateOrderApi
• Sylius\PayPalPlugin\Api\UpdateOrderApi
