Drupal 10 deprecation fixes

- Updated *.info.yml to be compatible with Drupal 10.
- Replaced fully qualified class names with imported class names for
improved readability.
- Replaced deprecated jQuery $.once to pure javascript .once library.
- Replaced deprecated hook_field_widget_form_alter() with
hook_field_widget_single_element_form_alter() for more granular control
over field widget form elements.
- Replaced deprecated getVocabularyId() with bundle() for retrieving
vocabulary IDs.
