haskell.packages.ghc924.purescript: allow building and test on Hydra

purescript now requires at least GHC 9.2 to be built due to the use of
OverloadedRecordDot. Consequently `haskellPackages.purescript` is marked
as broken. After eliminating the test dependency on the broken
utf8-light in language-javascript_0_7_0_0 we can build and test
purescript in the 9.2.4 package set.
