Remove comma from "Issue weight" system notes
Seems like issue weights still have the comma before the dot (tested on master / gitlab.com):
Seems like we have overseen this while doing https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/18593 and https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/5490.
