composer.json does not require all module dependencies

Problem/Motivation

There are a lot of module dependencies that are assumed will already be installed which are not if you just `composer require drupal/opigno_learning_path`. Not only modules from the Opigno suite are missing, but other contrib modules.

Steps to reproduce

The easiest way to replicate this is to use the DrupalPod extension (https://github.com/shaal/DrupalPod) and try to fix an issue with this module. Instructions on how to use DrupalPod are in the readme.

Proposed resolution

Update composer.json required section to include all module dependencies.
