Handle Documentation order_id update from Strapi admin panel

Relates to: https://feedback.strapi.io/customization/p/ordering-content-type-entries-in-the-list-view

Currently the creation and deletion of a documentation section will correctly increment and decrement an order_id using the beforeCreate and afterDelete lifecycle hooks provided by Strapi. As the default Strapi update function is used to update the entries on creation and deletion, handling the update of an order_id will cause a recursive update of all the entries order_ids.

A likely fix to this problem is to use a custom update "service" to update entries on creation, deletion, and update.

Strapi also seems to have a feature planned for future release that may help: https://feedback.strapi.io/developer-experience/p/ability-to-define-custom-indexes-in-the-schema
