Bug: edit-comment-event shows the original author instead of operator currently

[MaikoTan]

Summary

GitHub allows administrative users to change other users' posts, but the message that the bot pushed only shows the original author instead of the operator in the current event.

Exemples

This comment was posted by poor @MaikoTan or me, but got edited several times by @SaarChaffee , every time they change the content of the comment, the bot would say something like "@MaikoTan edited the comment in blahblah" instead of @SaarChaffee who is the one changed things.
