I’m a nix noob but I think this is a release of the nix package manager and therefore it’s unrelated to the version of the nix channel with nix packages.

Yes, it's the release 2.22 for nix, the cli tool. Not NixOS version 23.11, the operating system.

23.11 is the nixpkgs/NixOS version. This is the version of the Nix package manager. If you don't need the newer version then there is nothing to worry about. It doesn't effect the NixOS and nixpkgs software that you are installing.

This is like an Aptitude package manager update vs Debian version or a Pacman update vs Arch Linux version (not Arch has versions).
