Error when trying to save CKEditor text formats: 'quick_tips' is not a supported key

I can confirm am getting the same issue when i upgrade ckeditor to ckeditor 5

Hi,
I have resolved the "CKEditor 5 text formats" issue and created MR!5.
Kindly review it.

Thanks!

Thanks but the error is still there and preventing me to save the text format form even after applying MR!5

Hi guys,

Thank you for being interested in the module. I would recommend removing the lines below from the ReadmehelpMarkdown class.

 *   settings = {
 *     "quick_tips" = "",
 *   },

It's optional, see: https://api.drupal.org/api/drupal/core%21modules%21filter%21src%21Annota...

Also, please update code in the ReadmeHelpController class:

$admin_tasks = \Drupal::service('system.module_admin_links_helper')->getModuleAdminLinks($name);

Inject the service as a dependency of the class.

I had to do that, plus also remove this from ReadmehelpMarddown.php:

  /**
   * {@inheritdoc}
   */
  public function settingsForm(array $form, FormStateInterface $form_state) {
    $form['quick_tips'] = [
      '#type' => 'item',
      '#title' => $this->t('Quick tips'),
      '#description' => $this->t('You can use <a href=":readmehelp" name=":name">markdown syntax</a> like in [...]', [
        ':readmehelp' => Url::fromRoute('help.page', ['name' => $this->provider])->toString(),
        ':github' => 'https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet',
        ':name' => 'readmehelp-filter',
      ]),
    ];

    return $form;
  }

Please, inject services in the class constructor.

Sorry, I didn't even now what "inject services in the class constructor" meant 😅😇, so I asked ChatGPT and tried to provide a new MR accordingly.
