Better install experience

[ccjjmartin]

Purpose:

• Better install experience

Details:

• I hit issues during the install process due to a composer symfony version issue, I have put up a PR to fix those Add support for Symfony 5 #52. Overall though we need a process that doesn't involve composer for end users as composer results in "hard to install" experiences.

Options:

• Building a phar file like drupal-check: https://github.com/mglaman/drupal-check/wiki/Build-From-Source
