hls-fourmolu-plugin: Update ghcide dependency

```
src/Ide/Plugin/Fourmolu.hs:18:1: error:
    Could not find module ‘Development.IDE.GHC.Compat.Util’
    Perhaps you meant
      Development.IDE.GHC.Compat (from ghcide-1.4.2.2)
      Development.IDE.GHC.Util (from ghcide-1.4.2.2)
    Use -v (or `:set -v` in ghci) to see a list of the files searched for.
