nix-unit: 2.30.0 -> 2.34.0 (#513347)

  # We pin the nix version to a known working one here as upgrades can likely break the build.

  # Since the nix language is rather stable we don't always need to have the latest and greatest for unit tests

  # On each update of nix unit we should re-evaluate what version we need.
