Update Cabal submodule to whatever the final Cabal 2.0 release is
This is a release blocker and I want to file it here so we don't forget.
In fact, 2.0 head has already diverged from 8.2.1-rc1, see https://github.com/haskell/cabal/issues/4453 for some fall out (since we now have multiple "2.0" Cabals floating around.
