CKEditor 4 small fix

A small fix for old versions CKEditor. If you are using an old version of this editor, over time an annoying message about an outdated version may appear. Of course, you can update everything, but if everything suits you but you don't want to see annoying inscriptions, do the following according to the recipe from stackoverflow - find the editor configuration script and add the line -

config.versionCheck = false;

After that, we save the config, clear the caches, and work with the editor without annoying messages.
