Nix shell in docs wrong after winit update.

Ever since #10702, winit needs libxkbcommon-x11. This was mentioned in the docs for Ubuntu (since #11060), but not for other distros. I ran into this issue today when trying to run a bevy app with DefaultPlugins on my fresh NixOS installation. This should probably be mentioned on the docs.

Never mind, I didn't have my flake setup properly. For anyone who wants a working flake:

{
  description = "A basic flake with a shell";
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
  inputs.flake-utils.url = "github:numtide/flake-utils";
  inputs.rust-overlay.url = "github:oxalica/rust-overlay";

  outputs = { nixpkgs, rust-overlay, flake-utils, ... }:
    flake-utils.lib.eachDefaultSystem (system:
      let
	overlays = [ (import rust-overlay) ];
        pkgs = import nixpkgs {
          inherit system overlays;
        };
      in
      {
        devShells.default = pkgs.mkShell rec {
	  nativeBuildInputs = with pkgs; [
	    pkg-config
	  ];
          buildInputs = with pkgs; [ 
	    (rust-bin.selectLatestNightlyWith (toolchain: toolchain.default))

	    lld clang 

	    udev alsa-lib vulkan-loader
	    xorg.libX11 xorg.libXcursor xorg.libXi xorg.libXrandr # To use the x11 feature
	    libxkbcommon wayland # To use the wayland feature
	  ];

	  LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath buildInputs;
        };
      });
}
