Ck5 challenges in D11.2.x and D10.5.x

Yes I am dealing with this now on a contrib module. 10.5.x and 11.2.x both upgrade CKEditor5 to version 45.2.0, introducing breaking changes.

For the ckeditor_div_manager module it broke the plugin buttons. We had do the following change:

- import { icons } from 'ckeditor5/src/core';
+ import { IconCheck, IconCancel } from 'ckeditor5/src/core';

The difficulty is, to fix this issue with CKE5 v45.2.0, it seems to cause the same issues with the previous version of CKE5 44.x.x on Drupal 10.4.x and 11.1.x.

I'll do some tests with Drupal 11.2.2 and see what I can find.
