upstream is DEAD (the repo has a single branch named 14.0, no tags, and its last commit is 2022-12-06 — before frappe v15 existed), the branch IS the Frappe v14 line, this bench is v15 or newer, the repo is PRIVATE so the clone needs credentials, and NO FIXES ARE COMING. It was carried in the bench manifest but installed on NO site, so no restored database needs it.
