Needs support for Drupal ~10.1.0

Change core/jquery.once to core/once

Custom once code needs changes.

This feature was approved to be added, and it's needed and used in number of projects.

Avoid multiple executions in the JavaScript code.

Happy to add this new feature to the 9.1.x branch and maybe to 10.0.x
As we drpped support for Drupal 9 ( only trying to save time for Varbase 9.1.x and Varbase 10.0.x )

Please, have a look at comment #13
