representations which are not literal Nix values again.
This was fixed in upstream Nix in
https://github.com/NixOS/nix/pull/4012 (though only for eval, not in

also bumps our custom Nix 2.3 to a commit that includes the
cherry-picked fix from the PR above.

This adds scaffolding code for running the Nix language test suite.
The majority of eval-okay-* tests should eventually be runnable as-is
by Tvix, however the eval-fail-* tests might not as we intend to have
