Add Nix Flake

[justDeeevin]

The previous commit claiming to add NixOS support merely added a devshell. This flake fully packages Scope, in addition to providing a development shell. A NixOS user (with a flake config) can now install the app seamlessly.
The package includes a desktop shortcut. The keywords list in the shortcut has been left empty--I felt it more appropriate for one of you to decide upon fitting keywords.

Additional note: Right now the Desktop Icon is being pulled directly from this org's github avatar. It might be preferable to include the file in this repo or someplace more reliable.

Thanks for this, just added this 'help wanted' label so someone else (@bvvst or @zarc probably) could add keywords.

I'm not super familiar with Flake (I've only used it once before) so couldn't really give this PR a review of much value. How could I test this PR locally so we can merge it?

run it under a docker container

Building but not currently running on my machine... seems like a wayland thing, though.

Don't think this is a blocker to this PR, but still worth mentioning.

not really sure why it wouldn't work on wayland, it builds and runs completely fine for me on wayland (although i dont use nixos, i use endeavour)

Now that you mention it, I realize it's probably a me problem. I've run into that same error message with WezTerm as well, but only on my laptop. So it's probably something I'm messing up with my graphics config on here.

any updates on this PR?

[justDeeevin]

The desktop entry needs some keywords added. Also apparently some merge conflicts? Resolving now.

[justDeeevin]

I can't think of anything else that's been asked of me yet. Once we come up with some keywords for the desktop entry, it should be ready to merge.

Looking at some example in nixpkgs:
Vesktop uses the keywords: ["discord" "vencord" "electron" "chat"]
Discord has no keywords.
They both also use the categories ["Network" "InstantMessaging"]. Vesktop also includes the category "Chat"

Perhaps no keywords, just the three categories that Vesktop falls under? That would look like

categories = [
  "Network"
  "InstantMessaging"
  "Chat"
];

I'm hesitant to make this call myself since this isn't my app.

we should just go with ["discord", "chat"] for keywords, and the same categories that Vesktop uses
