How can I configure PHP-CS-Fixer to use tab for indentation?
I can see the indentation_type fixer
* indentation_type [@PSR2, @Symfony]
  | Code MUST use configured indentation type.
But how do I configure the indentation type? If I try to set 'indentation_type' => 'tab',, I am getting the error
[indentation_type] Is not configurable.
