New To Cabal - Initializing a cabal repo

file to edit: https://github.com/haskell/cabal-userguide/blob/main/src/new_to_cabal/04_initializing_a_cabal_repo.md

## Brief Summary

This chapter should give a new user all the information they need to start a cabal repo. It should cover manually initializing a repo , initializing with `cabal init --interactive`, and initializing with `cabal init`. The chapter should go into a brief introduction of the directory structure of a standard cabal package, but no go into so much depth as to explain the more complicated aspects (i.e. `Setup.hs`
