Order products by stock status

[Nessario]

Is your feature request related to a problem? It's been often a request from clients to order the products by stock status so the in stock products will always be listed first.

Describe the solution you'd like A more ideal way to handle this would be if products orderby would include stock status as a part of the default options.

Describe alternatives you've considered Been trying two approaches:

• Making use of post_clauses hook but that didn't lead to a clean/maintainable solution.
• Trying to make use of graphql_woocommerce_products_add_sort_fields hook to update the default options, but with latest updates it seems that it isn't possible anymore.

@Nessario The function that calls that hooks is no longer in used and new one with have to be added here.

With that hook, you would just have to register a new enumeration value to this type using the hook in the linked code, and you should be all good
