Update Drupal versions & Fix assignments

[BretFisher]

Drupal in the course is one major version out of date, and has issues with Postgres on M1/arm64 processors. Test and update the various lectures, and source code, with the latest mainstream versions.

Pin to drupal:9 and postgres:14 for now.

In addition, in the latest Drupal+psql, Postgres no longer works and MySQL/MariaDB are preferred.

NOTE: need to search for more drupal examples and change to mariadb

For these lectures:

9 is now EOL, and Drupal:10 should be what I test and update to.
