polysemy-plugin: fix tests

- polysemy-plugin was broken due to failing doctests:
  https://github.com/NixOS/nixpkgs/issues/71164.
- I submitted a PR upstream to fix this:
  https://github.com/polysemy-research/polysemy/pull/265.
- I've applied the patch of the PR here and moved the default
  "polysemy" attribute to "polysemy_1_2_0_0" because polysemy-plugin
  requires "polysemy >= 1.2.0.0".
- Move default "polysemy-zoo" attribute to "polysemy-zoo_0_6_0_1"
  because it is fixed by the polysemy-plugin changes and fixes issues
  with building "polysemy-RandomFu" and "knit-haskell".
- Removed packages no longer broken from
  "configuration-hackage2nix.yaml".
- Add cabal-doctest to setupDepends of polysemy-plugin.
