Add "How to Download and Install Drupal Recipes" to its parent menu

Documentation location/URL

https://www.drupal.org/docs/extending-drupal/drupal-recipes/how-to-downl...

Problem/Motivation

The parent page of this page I created had the instructions, but the limitation on characters meant it could not be elaborated on. As such I spun out installation instructions into a subpage, and added more explicit steps with more descriptions, to help alleviate some of the confusion I felt when I was trying to figure out how to install recipes reading the original page.

Proposed resolution

Add this page as a subpage to the documentation.
