Run ghcide under a nix-shell (or any other shell)

I tested this locally, works like a charm, thanks.

The only (very minor) annoyance is that ghcide doesn't restart if we change the command. I don't know whether there's an easy way to do that in atom (it's not a big deal anyways as there's probably no need to change this too often, so restarting atom is totally affordable in this case)

True, but maybe we can add some commands for it, e.g.

ghcide:stop
ghcide:start

Though I'm not sure how reliable that will be. — Restarting Atom is usually fast, specially if you disable a bunch of stuff you might not need (YMMV), for example:

"*":
  core:
    disabledPackages: [
      "archive-view"
      "autoflow"
      "background-tips"
      "exception-reporting"
      "github"
      "image-view"
      "link"
      "metrics"
      "open-on-github"
      "spell-check"
      "welcome"
    ]
    telemetryConsent: "limited"
    uriHandlerRegistration: "never"
  welcome:
    showOnStartup: false
