Paidy payments done via Woocommerce for physical_goods MID are not working. We are getting error 422 from Paidy with "payment_data[shipping_address]" is missing. This means that all physical goods MID merchants using Paidy for payments via Woocommerce will have failed payments.

This PR adds the shipping_address to the API request when the default shipping_address is the `billing_address

• Add a product to your cart and go to the checkout page.
• Fill in your billing info and select Paidy at the bottom.
• Proceed with the payment. You should be redirected to the hosted page.
• Proceed with the payment. A Paidy screen should pop up asking for information. This is good enough, you don't need to complete the payment.

This looks great. Very nice find. Not sure how long it would've taken me to figure this out 😅

@Resonious the hard part is that my changes weren't taking effect and I had no idea what was going on. I also couldn't debug or produce logs lol

I ended up having to run docker-compose up --force-recreate. I updated our docs https://www.notion.so/WooCommerce-Testing-Demo-9bbada14ee314a379e141f8d512dde4f

I also don't know why, but logs are not produced even when checking the 'Enable logging' box as described in our docs 🤔
