[Feat]: More sync between nixpkgs version and repo version

## What is your suggestion?
It would be nice if the NixPkgs version is always up-to-date with the latest release.

## Why do you want this feature?
In can only install code-server through nix due to some requirements, and I would like to always have the up-to-date version, specially important due to copilot/copilot-chat

## Are there any workarounds to get this functionality today?
I can modify the nixpkgs and build it locally.

## Are you interested in submitting a PR for this?
I may be interested to maintain nixpkgs version, but when I tried to modify the nixpkgs repository, I failed to compile due to some yarn errors, that I don't know if they are my fault or that this pkg needs to be compiled with some extra nix configs.
