`classy-prelude` does not build with `time >= 1.10` #204

classy-prelude does not build on ghc 9.2.1:

 ghc --version

bash-3.2$ cabal install classy-prelude

According to https://hackage.haskell.org/package/time-1.12/changelog, parseTime was removed in time-1.10. This succeeds:

cabal install classy-prelude --constraint='time<1.10'

I revised 1.5.0 accordingly, see https://hackage.haskell.org/package/classy-prelude-1.5.0/revisions/. @GeorgeCo Please try again (after cabal update!).
