[xmonad] question about code in XMonad.Actions.GridSelect

[Platon Pronko]

Hi!

I'm working on a PR right now. I've implemented the fix already, but I have trouble with tests -
  `stack test` uses random-1.1, and uniformR is not found there.

Should I use randomR instead? Alternatively, how can I specify that a newer version of random should be used?

Best regards,
Platon Pronko
