UI language

[Brand3000]

Thank you very much for adding the html-support feature. But what happened with the ui-language feature and its script setting? I see the comment "Not available". I need to change the UI language, but it seems that I can't do it, can I? In the previous version it worked. My config is:
` 'content-lang' => 'ru',

        'ui-language' => [
            'name' => 'ru',

            /**
             * Example 1: asset('js/ckeditor-fa.js')
             * Example 2: 'https://cdn.ckeditor.com/ckeditor5/34.0.0/decoupled-document/translations/fa.js'
             */
            'script' => public_path('core/ckeditor-ru.js')
        ],
