hashable 1.3.0 is broken on GHC 9.2.1. This enables building unordered-containers.

Motivation for this change
hashable 1.3.0 (the current stackage version) is broken on GHC 9.2.1 because it defines an instance for
Option, which has been removed from base. hashable_1_3_3_0 (already available in nixpkgs) includes a fix.Tests are still broken because
random(required byQuickCheck) has not yet been updated for GHC 9.2.1.With this change it is possible to build
unordered-containers(tests also won't compile because ofrandom).@cdepillabout I was motivated by your comment to fix this :)
