Support ghc 9.8

[alexfmpe]

On top of #31 but done as a separate PR as the dependent-sum-template lower bound is increased, which I guess can count as a breaking change?

EDIT: Oh probably not, since it's only a bound on the executable?
I tried only increasing the upper bound but it keeps picking up 0.1 unless I increase the lower one.
For the record, here's the error

Think this also needs a release of
obsidiansystems/dependent-sum-template@dfaf678

[alexfmpe]

@ali-abrar Might be able to just do
https://github.com/NixOS/nixpkgs/blob/e22b1a7d7b0e338cca6932ab5a3f16e20fcf1c32/pkgs/development/haskell-modules/configuration-ghc-9.8.x.nix#L91

[ali-abrar]

yeah, probably. but i already merged ;)

[alexfmpe]

RIght, I meant it more as a FYI for any other repos with a big blob of release.nix that can now be aggressively pruned down

[ali-abrar]

thanks for all the PRs btw

[ali-abrar]

released to hackage
