Evaluate use with Drupal and CKEditor 5

CKEditor 4 is officially reaching its end-of-life soon

At the end of Q2 2023 CKSource (the maintainer of CKEditor 4) ended security coverage for CKEditor 4: https://ckeditor.com/blog/ckeditor-4-end-of-life/

That being the case, the CKEditor Styles Combo Plus will need to be updated to fully support CKEditor 5 unless it is found to be redundant.
