Drupal 10 compatibility

Drupal 10 compatibility!

• Added Drupal check and Rector to lint code
• Added D10 CI job and test fixture
• Fixed deprecated code

Please note that this release is using forked versions of DrupalDriver and Behat Drupal Extension with required Drupal 10 related updates:

• https://github.com/drevops/DrupalDriver/tree/feature/drupal-10
• https://github.com/drevops/drupalextension/tree/feature/drupal-10

These will be removed in a new Behat Steps release as soon as the upstream projects support the required changes
