The 92 indicates that this version is based on ghc-9.2.*.
Given that we support a single GHC version at a time
(and avoid any CPP mess) I thought this might be appropriate.
This also allows bug-fix releases to different "branches",
i.e. publishing 92.x.x.(n+1) together with 94.y.y.(n+1) to
address some bug that affects both the ghc-9.2.* branch
and the ghc-9.4 branch. From a PVP perspective it might not
be ideal that we regularly bump major versions when the
API does not actually change much, if at all, but given that
brittany primarily is an executable and will probably have
a small set of reverse-dependencies this seems acceptable.
