Before	After

How to set up and validate locally

1. enable and configure zoekt for a namespace

2. enable search_add_archived_filter_to_zoekt feature flag

   echo "Feature.enable(:search_add_archived_filter_to_zoekt)" | gdk rails c

3. make sure the namespace has at least one archived project with searchable text. Since i created new projects with the default README, I searched for "To make it easy for you to get started with GitLab"

4. do a group code search (ensure that Zoekt code search is enabled in your user preferences)

5. verify the include archived checkbox shows up and by default is unchecked

6. verify archived results not returned

7. select include archived and re-run the search

8. verify archived results are returned
