Fix visit docs for Racket & support racket-xp (#3373)

* Fix visit docs for Racket & support racket-xp

- Fix Racket's +lookup/documentation in the same way as
  f20f477a44
- Support the +xp feature which enables racket-xp. When it's not
  enabled, default handlers to the traditional racket-repl
  (which requires users to run code first)

* PR feedback

* Replace add-hook! with add-hook
