Improve support for more libraries than Drupal Starter

[amazingrando]

CLI technically only supports the Drupal starter still. You can use others, but it requires knowledge of the commands.

Since we have starters technically available we should allow for commands that will spin up for WordPress and Gatsby.

Closing this ticket so we can revisit in the future with a more focused effort. The CLI currently supports 2 starters.
undefined - Platform agnostic starter
undefined - Drupal theme starter
