more information rfc link results in 404

[st-h]

ember-optional-features@1.0.0 shows the following for further information. The rendered rfc link however ends up in a 404:

  default-async-observers (Default: false)
    Makes all observers asynchronous (unless manually indicated as synchronous when calling addObserver/observes).
    More information: https://github.com/emberjs/rfcs/pull/494

Should we change the rfc link to the archive (assuming this is the official archive - just found the link through google)?
https://emberjs.github.io/rfcs/0494-async-observers.html

I updated the rendered link in that RFC (so it works again), and I'm happy to updated our messages to link directly to the final location (https://github.com/emberjs/rfcs/blob/master/text/0494-async-observers.md).
