Fix 'Installation and configuration' step 4 on project page

On the project page https://www.drupal.org/project/editor_advanced_link → it says:

4. else, add the "title", "class", "id", "target" and/or the "rel" attributes to the "allowed HTML tags" field (only those whitelisted will show up in the dialog)

Unfortunately, CKEditor won't allow you to do this

E.g. admin/config/content/formats/manage/full_html at the 'Filter settings' for "Limit allowed HTML tags and correct faulty HTML" it says:

With CKEditor 5 this is a read-only field. The allowed HTML tags and attributes are determined by the CKEditor 5 configuration. Manually removing tags would break enabled functionality, and any manually added tags would be removed by CKEditor 5 on render.
