ERROR: npmDepsHash is out of date

The package-lock.json in src is not the same as the in /nix/store/s472jwn7860nji3ri376063mani5snv3-docs-npm-deps.

To fix the issue:
1. Use `lib.fakeHash` as the npmDepsHash value
2. Build the derivation and wait for it to fail with a hash mismatch
3. Copy the 'got: sha256-' value back into the npmDepsHash field
