Upgrading DrupalEasy.com to Drupal 9, Part 3

The process is mainly based on the Upgrade Status module's report and was recording during the weekly, 2-hour DrupalEasy office hours (provided to alumni of Drupal Career Online).

Part 3 includes:

- Upgrade Status, uninstalled Composer Deploy, split out Upgrade Status config.
- Updated Field Group module to 8.x-3.1
- Updated Google Analytics to 8.x-3.1, exported updated config.
- Added drupal/core-dev (which involved some fun/interesting/educational Composer dependency version conflict sleuthing) to assist with Upgrade Status report.
