Fix flake

[teto]

I've tried using the flake in my project referencing jupyterWith.overlay but it failed with error: attribute 'jupyter_contrib_core' missing.
I fixed that and made it pass nix flake check. There is a breaking change though.

Thanks for the PR, I'm not very experienced with Flakes yet, this is useful. I launched tests.

I have the impression that the changes to the two overlay files are superficial, can you keep the original?

@GTrunSec Since you wrote the Flake, can you take a look at the PR?

nix flake check requires the parameters to be called prev and final so I can't keep the original.

I will look into the CI failure. One cool tool though is https://github.com/edolstra/flake-compat/ that allows to run a legacy nix-shell while using the flake as a source of truth (mentioning this since I see the failing job comes from a devshell.nix).

I fixed the example flake, should be good now.

This is working now, thank you!

I'm running into this issue (an error about jupyter_contrib_core not being found) when trying to build a docker image - I'm trying to build this:

let
  pkgs = import <nixpkgs> { system = "x86_64-linux";};
  jupyter = import (builtins.fetchGit {
    url = https://github.com/tweag/jupyterWith;
    rev = "6024eb9329c5f47102adc26f541712121bba62d4";
  }) {inherit pkgs;};

  jupyterEnvironment = jupyter.jupyterlabWith {};
in
    pkgs.dockerTools.buildLayeredImage {
      name = "jupyter";
      tag = "latest";
      created = "now";
      contents = [ jupyterEnvironment ];
      config = {
          Env = [
              "LOCALE_ARCHIVE=${pkgs.glibcLocales}/lib/locale/locale-archive"
              "LANG=en_US.UTF-8"
              "LANGUAGE=en_US:en"
              "LC_ALL=en_US.UTF-8"
          ];
          CMD = [ "/bin/jupyter-lab" "--ip=0.0.0.0" "--no-browser" "--allow-root" ];
          WorkingDir = "/data";
          ExposedPorts = {
              "8888" = {};
          };
          Volumes = {
              "/data" = {};
          };
      };
  }

I'm not sure if the issue is in the way I import pkgs or whether there is an issue with jupyter_contrib_core?

looks good, thanks for your work.
