Copy Comments to Related Issues doesn't work with "current comment" for event-based actions
If you configure a Copy comments to Related Issues post-function on an event-based action that responds to the Issue Commented event to copy the "current" comment (the comment that caused the event), nothing gets copied. this is because the "current" comment detection doesn't work.
Instead, we should use the comment passed as part of the event, in context.comment
Also updated the label of the option on the post-function configuration screen
