docs: Fetches the translated description for the given datatype.
  
          The given value will be converted to a `numpy.dtype` object, matched
          against the supported datatypes and the description will be translated
          into the preferred language. (Usually a settings dialog should be
          available to change the language).
  
          If the conversion fails or no match can be found, `None` will be returned.
  
          Args:
              value (type|numpy.dtype): Any object or type.
  
          Returns:
              str: The translated description of the datatype
              None: If no match could be found or an error occured during convertion.
