Drush 12 compatibility

Fixing Version info.

An open and honest question in addition to the one in the IS: would we want to opt for auto-wiring instead of adding the create methods? It's the new in, hip and pop thing available in Drush 12.5. At least using create methods gives us a little more backwards compatibility.

@japerry, I have pushed changes in the MR now. Please review again. As you can see in the comments, I also manually tested with the two combos that IMO make some kind of sense: Drupal 10.1+Drush 11 and Drupal 10.2+Drush 12. But as I wrote this note, I thought of yet another combo that is sensible in some cases: Drupal 10.1 + Drush 12. Here's the output for that test, which also indicates that the combination works ok with the branch:
