Sort by filter that defaults to "relevancy" which is our current ranking but also allows seeing the results ordered by "Most recent" (based on date posted) or "Most Viewed".
As a Commons user, I want to be able to sort search results by different criteria.
- A "Sort by" filter is added that allows users to change the order of search results
- The sort filter would appear on all tabs
- The sort filter should have the following options:
- "Relevancy" (default)
- "Recency" (based on date posted)
- The sort filter should match the following design on desktop. This task does not cover the mobile UI (this will be done as part of T258615)
