Update the make-init-project-drupal target

Overall goals:

• Use DDEV instead of Lando
• Use a modern Drupal (10? 9? give the user a choice?)

Following @sensespidey's recent work, we can now do the following and be in a position to merge this branch:

• Migrate and re-enable tests in CI to use new init target code (ddev, not lando, etc.).
• Decommission the old lando target and all associated code.

Additional nice-to-haves if time (starting from here):

• Initialize a .gitlab-ci.yml with our usual DDEV-in-CI stuff.
• And a behat.yml (and attendant dependencies, features context classes, etc).
• DDEV chromedriver add-on, too.
• Implement: Migrate deprecated gitlab-runner to gitlab-ci-l... (#138 - closed)
• Look at Add init-drupal-profile target (#145)
• Look at Lacking environment variables on project initia... (#146)
