Draft: Restore sort_value_stars_asc to options hash

What does this MR do and why?

A script identified #sort_value_stars_asc as unused, and in digging deeper, it looks an awful lot like this method, which returns a string used as a key in the hash returned by #projects_sort_options_hash, was removed by accident; indeed, there's 2 keys listed for sort_value_stars_desc, which would override the initial declaration. It looks like this change was made in the midst of a large ~"maintenance::refactor" and ~frontend transition MR so it might simply be something that was missed.
