Include GHC 9.4 in CI ?

[andreasabel]

I have come here because I get a library problem with unix under the ubuntu-22.04 virtual environment when used with GHC 9.4.2 and static linking:

/home/runner/.ghcup/ghc/9.4.2/lib/ghc-9.4.2/lib/../lib/x86_64-linux-ghc-9.4.2/unix-2.7.3/libHSunix-2.7.3.a(Files.o):
function ghczuwrapperZC1ZCunixzm2zi7zi3ZCSystemziPosixziFilesZCmknod: 
error: undefined reference to '__xmknod'

(See https://github.com/agda/agda/actions/runs/3603326548/jobs/6071389168#step:11:38.)

Maybe such problems could be caught if the CI here included GHC 9.4 and also something that tests static linking (--enable-executable-static).

Is there a reason that GHC 9.4 isn't included in the CI? After all, it ships with unix.

Mostly that we don't get paid.

A PR adding GHC 9.4 to the build matrix would be welcome.
