jQuery event dialog:aftercreate is deprecated in 10.3.0 and is removed from Drupal:12.0.0

See the issue fork for the required changes to fix this issue. Only thing to check is, if the minimum required core version has to be bumped to 10.3 with this fix.

Drupal 10.2. is supported at least until December 2024, also given that almost 50% of Drupal 8+ installations are running on outdated core I think this issue should either be postponed or at least require 10.3 version on composer.json.
