Update the default GHC version to 9.6.4.

Should be merged after https://github.com/IntersectMBO/cardano-node-emulator/pull/24, so that we have CI checks to catch mistakes.

Sadly we cannot update to 9.6.5 as easily, in this case entering the flake fails as follows:

          821|         else

       Did you mean one of 3.10.1.0, 3.10.2.0, 1.10.0.0, 1.10.1.0 or 1.10.2.0?
