Support nodejs modules from github

[dacevedo12]

npm supports installing directly from github repos, which comes in handy as sometimes, maintainers take a long time to publish new versions to npm

https://docs.npmjs.com/cli/v9/configuring-npm/package-json#git-urls-as-dependencies
https://docs.npmjs.com/cli/v9/configuring-npm/package-json#github-urls

perhaps the structure in the package-lock changes a bit, causing makes to fail when installing the deps

Tested with npm i --save https://github.com/cloudinary-devs/gatsby-source-cloudinary#19a2115fdf876c55ff74756e6dfd8d775bad636c

note: It works well using the tar.gz npm i --save https://github.com/cloudinary-devs/gatsby-source-cloudinary/archive/19a2115fdf876c55ff74756e6dfd8d775bad636c.tar.gz

npm supports both, so it would be worth documenting this behavior in case this becomes a won't fix

@dacevedo12 As we recently migrated to node2nix, it would be nice to tests if this works now.

[dacevedo12]

Seems node2nix is capable of it, but it doesn't find the git binary

error: builder for '...' failed with exit code 1;
       last 10 log lines:

       >   syscall: 'spawn git',

@dacevedo12

Maybe by adding buildInputs via packageOverrides as shown here

[dacevedo12]

It only worked at makes level (make-node-js-modules/default.nix), by adding __nixpkgs__.git

git via ssh doesn't work but that's a limitation from node2nix svanderburg/node2nix#309

git via https works fine with the aforementioned patch

@dacevedo12 A PR adding git to the builtin is welcome!

[dacevedo12]

Addressed in #1286

Thanks @dsalaza4 node2nix sure was an improvement!
