Documentation of exposed Haskell packages for code.world

Hello! Thanks for maintaining this project!

I just want to ask something about the documentation.

Do we have a complete list of exposed Haskell packages for use on the online site? (https://code.world/haskell#). I noticed that I could import `Data.Vector` (vector) and `Control.Monad.State` (mtl).

The current reference and appendix sections on the guide page are a good start to see the documentation for code-world and other related high-level APIs, but I believe it would be better to let the user know the list of other "low-level" exposed packages/modules so they can get the general idea of what's available to use and search the doc for them somewhere else in case they'd prefer to use those modules directly for whatever reason.

Thanks \:D!

Start with the online Haskell site and the guide's current reference and appendix sections. Verify the availability of Data.Vector and Control.Monad.State, then identify the other exposed low-level packages or modules. Done means the guide provides a complete, searchable list of exposed packages or modules.
