The old CKEditor module (which integrates with CKEditor 4) has been removed from core in Drupal 10 and is replaced by a new "CKEditor 5" module that integrates with CKEditor 5. The older version still appears as 'CKEditor' when displayed, such as on the extension page.
Switch to CKEditor 5 for new installations and add notice to recommend switching to CKEditor 5 on existing sites.

Hello, Droopler 3.1 is not compatible with Drupal 10 yet, the compatibility will be a part of upcoming 3.2 version. We've got some work in progress, but it will take some time until we fully test it.
