[Shopify] Update configuration page

[antmonnier]

Many features have been added to the Shopify Bridge configuration page since the last documentation update.

We need to update the Shopify Bridge configuration page to include the new features. All images are already in the images folder.

An example of recently updated configuration pages is Deliveroo Bridge configuration page. Note that Deliveroo shows the whole order section in one image, but we decided to split into subsections for Shopify, as the section was too long.

Thanks @antmonnier! Just a quick question: in the Payments section, is there a trick to figure out the payment name used on Shopify?

Not sure, but this post suggests that the current best option is to place test orders.

Thanks, that makes sense. I used this approach in the docs.
