[PORT] Fix wrong line number in code search result (gitea#29260) (#2619)

Port [Fix wrong line number in code search result (gitea#29260)](https://github.com/go-gitea/gitea/pull/29260)

PS: also added [`-e`](https://git-scm.com/docs/git-grep#Documentation/git-grep.txt--e) before passing the keyword (my bad)
