I don't think we want to expose this orphan, it might conflict with other instances in ghcide etc.

This instance used to be defined in HLS itself before it was removed as part of this "drop support for ghc 9.0" PR:
https://github.com/haskell/haskell-language-server/pull/3875/files#diff-380432f16b40730b2d63e7ec74a15219c0efa602f03c884837c9e27cf0cc655bL126-L129
Do you have ideas about how the show instance could be defined for ghc 9.0 in hiedb? Declaring it manually with moduleNameString "inlined" doesn't sound appealing..
Is it even worth it resolving that hls TODO or would it be better to just remove it?
A third option that comes to mind: since hls dropped ghc 9.0 support perhaps we could drop support for it in hiedb as well which would make this workaround unnecessary.
