feat: vscode completionModel

[saylesss88]

Add: copilot completionModel setting for changing models declaratively

Add: The following required arguments to vscode/default.nix:

# vscode/default.nix
{
  pkgs,
  config,
  lib,
  ...
}: {

Add: The following to userSettings in vscode/default.nix:

      userSettings = {
        "vim.handleKeys" = {
          "<C-p>" = false;
          "<C-f>" = false;
          "<C-n>" = false;
          "<C-b>" = false;
        };
        # "github.copilot.advanced.completionModel" = "gpt-4";
      };

NOTE: It is currently commented out, choose your desired completion model and rebuild. If you get errors related to ~/.config/Code delete the Code directory and rebuild. It will be repopulated on rebuild.

I'm down to uncomment this. I believe that the default model is in fact gpt-4, but I like having this here so I know where to change it.

Also we'll need to figure out how to configure roo-code

I thought the "roo-cline" was roo-code. When I launch VSCode from my intel it brings up the AI settings and bookmarks right away. I am pretty unfamiliar with VSCode though so you'll have to let me know what you mean. Do you want me to create a roo-cline derivation like I was talking about?

[GregHilston]

Ah no worries. Take a look at this settings UI on my Windows (non-nixOS machine):

However for some reason, on my NixOS machine the Language Model drop down is not rendering... I wonder if this is just a Roo Code issue, and has nothing to do with my NixOS machine. I can provide a photo of the NixOS screen tomorrow.

Here's that same photo on my NixOS. See how we do not have the Language Model drop down? @saylesss88

Ok, I see what you're talking about. I discovered that roo-cline is now in Nixpkgs, I added a PR with the official Nixpkgs version.
