Mention on the Wiki that `Start Trace`/`End Trace` way is not needed when using anim notify

[Atulin]

It was not clear enough I suppose, because I was looking for all sorts of weird ways on how to handle the notify. I had the start trace and end trace nodes, and they would seemingly overwrite the anim notify trace.

Turns out, that neither of those nodes are needed with a notify. The notify just automatically triggers the event.
