Linear username should be displayed in a synced Linear comment on Github #57
Description
Right now, synced comments from Linear are posted in the name of the integrating user.
To avoid confusion, the name of the Linear user should appear in the comment, either in the footer alongside "synced from Linear" or somewhere else.
Ideally, comments wouldn't be posted on behalf of the integrating user but rather by the linear-sync.com application. (e.g. so the integrating user's name and avatar doesn't show up at all for a comment that doesn't involve them.) But this is a stretch goal, I think :)
