Allow GHC 9.0 & base 4.15

[ksqsf]

This is trivial. Just updating the upper bounds of butcher and multistate (PR) should be OK!

This is needed to make the haskell-language-server brittany plugin available in hackage

base-4.17 (for GHC 9.4) also works fine, adjusting the bounds on hackage again would be great!
