~~the import quickfix seems broken on 9.4: #3195

I have a suspicion that the diagnostic messages were changed just enough to break our regexes, which makes that possibly: #2014~~

nope, hls-refactor-plugin just isn't up yet

ghc-exactprint for ghc-9.4 released now!

brittany is no longer in maintenance: lspitzner/brittany#377

We may not want to keep the support for brittany for GHC versions >= 9.2.
