ci: Bump 9.2 and 9.4 minor versions

The stack CI already tests against 9.2.7 instead of 9.2.5 (as the cabal
file said), since we just specify the major version of the LTS resolver,
and lts-20 is up to 9.2.7 by now. Not much has changed since 9.2.5, but
update the haskell-ci workflow regardless. Likewise, 9.4 can be bumped
one minor version, so do that as well.
