README: Update usage example (#619)

Previously the example would blurt trace: WARNING: `cleanGit` called on /home/ben/code/trec-car/mediawiki-annotate without a `name`. Consider adding `name = "mediawiki-annotate";` trace: WARNING: A `ghc` argument was passed for source this has been deprecated in favour of `compiler-nix-name`. Using `ghc` will break cross compilation setups, as haskell.nix can notpick the correct `ghc` package from the respective buildPackages. For example use `compiler-nix-name = "ghc865";` for ghc 8.6.5
