Ship with NixOS by default

Just a feature request

I guess I mean it should not require fetchTarball import.

I fear that this might be a bit too hacky and little-maintained for this to happen, especially considering that it's unclear what versions of vscode it should support (we can't just say "current one" because you have no guarantee that that's indeed the one that clients will connect with).

@Ten0 I don't see much differences considering NixOS only lives for 6 months, and you'd have to enable the hack in configuration.nix.
