Update template to GHC 9.4.4

[kutyel]

Hi, this template looks amazing and it is just what I was looking for!

However, since it is 3 years old and I'm trying to build it with an M1, stack and ghc versions are too old, maybe this could be updated? 🙏🏻

Thanks in advance!

Hey,

Just last week I came back to the project to try out ghc 9.4.* incremental builds and I had a lot of problems it complains just trying to build, starting with base.

I tried to bump up dependencies to the last version, but then it complains on some changes. (Opaleye and Morpheus) I'm working on it, also working on a nix base build up, I think it will help on the M1 build.

I'll make a PR when it's ready and link it here.

Disclaimer: Don't have much time these days, don't know how much time will spend on it, maybe I'll neve end it. Maybe other contributors can try too.
