Ordering of guides on doc site

@azurecurve I have added support for menu order and also post edit table list can now be ordered by menu_order, apart of course, the actual front end now also will work when you pass order=“ASC” orderby=“menu_order” to the shortcode (done already for plugin guidelines)

Let me know if this resolves the issue.

The new menu order support applies to all 3 plugin guidelines, user guides and developer guides.
