If a comment dismisses a review, we need to load the reviewer to show whose review has been dismissed. Related to: https://github.com/go-gitea/gitea/blob/20b6ae0e5399cfc22c6a0989d8e520194e920bdd/templates/repo/issue/view_content/comments.tmpl#L765-L770 We don't need `.Review.Reviewer` for all comments, because "dismissing" doesn't happen often, or we would have already received error reports.
