\Drupal calls should be avoided in classes, use dependency injection instead

Please review MR.

It only resolved the \Drupal calls should be avoided in classes, use dependency injection instead errors. We should address all coding standard issues raised by phpcs.

Awesome, it resolved all phpcs coding standard issues. It can be merged now.

The advice from #4:

We should address all coding standard issues raised by phpcs.

Is not great advice, unfortunately. There's an existing issue at 🐛 Coding standard Needs review to already do that. The 2 issues overlap and change things differently which makes it harder to pick what to do.
