build(nix): refresh npmDepsHash for the 2.0.0 lockfile

The release bump rewrote the root version in package-lock.json, which is part of what fetchNpmDeps hashes, so the recorded hash stopped matching. Same change as the nix bump PR; carried here so this branch's own nix build can pass. A rebase after either lands drops the duplicate.
