fix(gs/xanthous): fix build failures caused by dependency updates r/2286

The following changes in dependencies of xanthous broke the build and
have been fixed in this CL. Thus we can reenable CI for xanthous.

* random 1.2.0 removed the Read instance for StdGen, so we need use
  System.Random.Internal to un-newtype StdGen into an SMGen in the
  appropriate places as that type still has a Show and Read instance.
  Requires a new direct dependency on splitmix as well.

* witherable 4.0 renamed Data.Witherable into Witherable and no longer
  exports Filter.

* random 1.2.0 probably also broke the Function instance for GameState
  which contains a StdGen. I'm not exactly sure which change exactly
  triggered this, but the fix is easy enough: We implement a Function
  instance for SMGen using functionShow allowing us to write a Function
  instance for StdGen using functionMap. I've put these instances into
  Xanthous.Orphans.

* hgeometry 0.12.0.0 removes the triangulationEdges function (which is
  also not mentioned in the changelog, so I'm not sure if there's a
  replacement yet). Fix by pinning to 0.11.0.0 for now.

* hedgehog-classes: relax bounds on semirings
