Building with ghc-lib-parser-9.0.*

[re-xyr]

stylish-haskell-0.14.0.0 supports GHC 9.0 & 9.2 now, but it's difficult to integrate it into HLS for GHC 9.0 because it uses ghc-lib-parser-9.2.* and ghc-lib-parser-ex-9.2.*, while other formatters still use ghc-lib-parser-9.0.*. It'll be nice if there could be a compile flag that allows stylish-haskell to build against ghc-lib-parser-9.0.* and ghc-lib-parser-ex-9.0.*.

Agreed. Porting from 8.x to 9.2 took a long time, but I expect the differences between 9.0 and 9.2 to be smaller.
