Preamble - What do we mean when we say cabal?

file to edit: https://github.com/haskell/cabal-userguide/blob/main/src/preamble/01_what_do_we_mean_when_we_say_cabal.md

## Brief Summary

The purpose of this chapter is to clear up some of the ambiguity around the overloaded term "cabal". We at least want to cover these four terms:
- cabal-install - the cli
- Cabal - the hackage package
- cabal.project - The configuration file
- .cabal - The package specific configuration file

If there are other cabal related terms that might be confusing, this would be a good place to precisely define them, and distinguish them from other cabal related things.
