Add Drupal Mega Menu to Contributed modules for menus doc page

Problem/Motivation

It looks like Drupal Mega Menu ( https://www.drupal.org/project/we_megamenu → ) and The Better Mega Menu ( https://www.drupal.org/project/tb_megamenu → ) are the two of the most popular Mega Menu modules.

But Drupal Mega Menu ( https://www.drupal.org/project/we_megamenu → ) is missing on https://www.drupal.org/docs/extending-drupal/contributed-modules/contrib... → .

Steps to reproduce

Proposed resolution

Create a Guide (or Page) under https://www.drupal.org/docs/extending-drupal/contributed-modules/contrib... → for Drupal Mega Menu ( https://www.drupal.org/project/we_megamenu → ).

Remaining tasks

User interface changes

API changes

Data model changes
