Set up the translations module 
 Overview
You can send for translation all ASP.NET Core widgets, both built-in and dynamic, using the Translations module. 
By default, Sitefinity CMS has a registration only for the Content block widget.  
You must explicitly register all other widgets in the translation module settings. 
Register a widget for translation
To create a new registration, perform the following: 
    - In Sitefinity CMS backend, navigate to Administration » Settings » Advanced.
- In the left navigation, click Translations » Strategies. 
- Create a new entry of type DecoupledControlStrategy.
 Or enter the full name of the strategy manually: Telerik.Sitefinity.Translations.Strategies.DecoupledControlStrategy
- Enter the name of the widget.
     NOTE: For a list of built-in widget names, see Sitefinity GitHub repository » ViewComponents.  
- In PropertyMappings, list all of the properties that you want to translate. 
 For more information, see  Translations module settings. NOTE: Nested properties are separated by a period (.) in the path.
