Add "frequently visited" sort option to groups GraphQL query

For https://gitlab.com/gitlab-org/gitlab/uploads/b251a944440ef1ff5679b2368566b528/Organization___Overview___Dropdown.png

On the Organization front page we need to be able to display the 5 most frequently visited groups. To do this we need a sort option added to the GraphQL query that is being built in #409311 (closed)

Implementation guide

Needs refinement, we should be able to use data from #431043 (closed)
