Error message on Status page

Problem/Motivation

When installing CKEditor IndentBlock on Drupal 10.4.7, the Status report (/admin/reports/status) reports an error about the missing library. The IndentBlock documentation ( https://www.drupal.org/project/ckeditor_indentblock → ) says this is no longer needed, and the plugin works find with CKEditor 5. This seems like a false error report.

Steps to reproduce

1. On a Drupal 10 website, isntall and enable the ckeditor_indentblock module.
2. Run update.php and clear caches.
3. View the Status report. The following error is shown:

  CKEditor IndentBlock
  Plugin not detected
  You will need to install the "Indent Block" CKEditor plugin under the libraries path before enabling this module. Get the plugin from CKEditor.com.

4. Confirm that IndentBlock works just fine when editing a web page.

Proposed resolution

Address reporting of missing library when the library is actually not required.
