Remove orphan CSS selectors in maniphest/task-summary.css
Summary:
* `maniphest-task-updated`
** Added in rPdf0c3df3cc6dbaa151e1b32ff4e01052eb3dad3e, usage removed in rP018de5dec742b6a38d02710670c1dd30101f5b9f by deleting `src/applications/maniphest/view/ManiphestTaskSummaryView.php`
Test Plan: Grep the code for each CSS selector (`grep --exclude="*.css" -R 'some-search-string' .`), also do partial searches, get no results.
