[racket] Scribble: "Warning: some cross references may be broken due to undefined tags"

Thank you Matthias and Danny.

In the instructions at
<http://docs.racket-lang.org/planet/Developing_Packages_for_PLaneT.html>,
I was on the early step "6.2.2 Create Documentation". Instead of
trying to get the docs "perfect" at this step, it sounds like I should
have forged ahead a few steps to the sort of activities in "6.3 Build
a Distribution Archive".

If today were the "docathon" Sunday in October, I'd take a stab at
reordering the steps, or, adding at 6.2 a sidebar with Matthias' tip.

Although I had another name in mind, I think you've convinced me
instead to call it, "My Little Planet Package: Friendship is Magic".
Let the brony jokes commence.
