Update to GHC 9.10

[ulysses4ever]

Bounds on deepseq, base and template-haskell will have to be bumped, routinely. But there's one actual roadblock so far:

• recursion-schemes is our dependency and can't build with 9.10 due to

  • Can't find interface-file declaration for type constructor or class GHC.Base.Functor recursion-schemes/recursion-schemes#160

• symbol is our dependency and depends on older containers. Somehow, it builds fine locally but Haskell-CI with all its cleverness does something that makes it fail (e.g. https://github.com/ulysses4ever/gibbon/actions/runs/9504818670/job/26198314154?pr=2)

  • I reported upstream: bump containers upper bound to support GHC 9.10 mainland/symbol#5 and even with the trustees symbol: bump containers upper bound haskell-infra/hackage-trustees#407 but the package seems pretty dead, so I'd suggest switching to infer that provides a similar service. Here's the patch:
    • Switch from symbol to intern as the former seems dormant #262

• same deal with mainland-pretty and language-c-quote

  • fortunately, there’s an active steward for this package, so it’s resolved
  • the bump for language-c-quote is done early July
