Add 'Sort by' Option to Topic Content Widget with Default Selection on Page Load

[krishnagopal_sn]

I want to add a "Sort by" option to the topic content widget, which is available out-of-the-box, so that it is selected when the page loads. The page I'm working on, which contains this widget, is located at https://dev****.service-now.com/esc?id=emp_taxonomy_topic&topic_id=ecc49ba7c3053010069aec4b7d40dd89 .
