HACKING.md : part about ghci outdated?

[andreasabel]

Stumbled over HACKING.md and tried it out:

filepath/HACKING.md

Lines 20 to 21 in 7139cd3

	The `.ghci` file is set up to allow you to type `ghci` to open the library, then `:go` will regenerate the
	tests and run them.

$ make gen
runhaskell Generate.hs

$ ghci
GHCi, version 9.4.3: https://www.haskell.org/ghc/  :? for help

Yeah, this doesn't seem to work anymore.
cabal repl fails in a similar fashion.

Maybe it is just cabal test which works nowadays?
