Drupal 10 compatibility fixes

Please read about this core change in Drupal 9.2:
https://www.drupal.org/node/3158256 →

They write about that up until 9.2, there was no once() and core/once, there was just the $(' ... .').once() and core/jquery.once. So if changing that library means the core_version_requirement should be ^9.2 minimum as the module's JS will break on those older Drupal versions with an undefined function error. And since Drupal 10 is not shipped with $(' ... .').once() and core/jquery.once, I changed the core_version_requirement, too.

Please review and verify.

Thank you for the MR and apologies for the delay, this has been merged in a new 2.x branch.
