Problem: we've recently supported ghc-9.10.1, but it's not tested by CI. Also we're still testing ghc-8.8.4, which is rather old and causes some troubles when updating Nix dependencies.
Solution: add 9.10.1 to tested GHC versions, remove 8.8.4.
Problem2: CI is triggered only on push, so it won't work in case of PRs from forks.
Solution: trigger it on PRs as well.
