Enhancement: Create a normal channel in entries instead of products being within "Shopify" #134

Description

This way our products will be structured and located in the same way as all the other entries making them more versatile and a better AX as products are in the same area of the CMS as our entries. It also leans more into the Craft 5 eco-system of "everything being entries".

Is there a reason I'm not aware of why it has been handled to create a separation between products and entries?

I'm tempted to investigate this route by:

1. Creating a products channel
2. Creating a product entry type
3. Adding a selection of Shopify fields (readonly would be easiest, but ideally the webhook could work both ways and data can be managed in both places)
   • Product ID [String]
   • Price Range [String]
   • Variants
4. Work with the Shopify webhook to connect to Craft and link the product entry to Shopify by the product id. Using this connection we can use the delete/update/create webhooks to keep our products entries up to date.
