fix: replace removed nodePackages_latest with top-level packages

nodePackages has been removed from nixpkgs as unmaintainable.
Migrate to top-level equivalents:
- nodePackages_latest."@astrojs/language-server" → astro-language-server
- nodePackages_latest.bash-language-server → bash-language-server
- nodePackages_latest.prettier → prettier
- nodePackages_latest.typescript-language-server → typescript-language-server
