Bump nix npmdepshash

[rgoulter]

For the Nix stuff added in #772, following #808.

Each time the javascript/package-lock.json updates (and it has been updated since the last time flake-modules.nix was updated in #808), someone who likes nix should run something like:

nix run nixpkgs#prefetch-npm-deps -- javascript/package-lock.json 2>/dev/null
# update npmDepsHash with this value

to update the value of the npmDepsHash in the flake-module.nix.

Thank you @rgoulter . I think it will be nice to add inside the documentation, (maybe at the setup page?) some information about nix, including the info added in this PR. What do you think?

Right, it would be good to get #775 done.

I think the right place to add it is near the installation documentation. -- a command like nix run github:paritytech/zombienet is roughly equivalent to "download the latest build of zombienet and run that".

I'll send a PR with some documentation briefly explaining Nix, and a couple of useful ways of using it.

including the info added in this PR.

Ah, I see that the docs do have a "development" page.

Yes, I think it would be useful to add the same details I included in this PR in the "development documentation". Albeit, the prefetch command is already mentioned in flake-module.nix.

# this should be updated on each dependency change (use `prefetch-npm-deps` to get new hash)

Thank you so much @rgoulter ! That would be great - and will close #775 as well. Feel free to add it as a "fixes #775" in that PR in order to close once merged

Besides the comments concerning Documentation this looks good to me
