Create a 2.x branch

Problem/Motivation

The 1.0.x branch currently supports Drupal 8, 9 and 10. This means we can't use newer language features like constructor property promotion. A new 2.x branch would also allow us to make BC breaks such as changing service parameters and other refactors.

• Profit

Remaining tasks

Identify other areas to be refactored. Possibly create follow up tickets so we can get the ball rolling.
