[racket] DrRacket package suggestions

That sounds like a good idea. 

I think you want the `pkg-catalog-update-local` function from
`pkg/lib`. I should update the GUI package manager to use that
function, too.

(I think the GUI package manager's implementation was first, and I must
have intended to merge them after creating the variant in `pkg/lib`.)
