ci: upgrade Nix from 2.3.12 to 2.5.1
Due to changes in how Nix handles Git refs we need to specify `refs/tags/` prefix in `package.json` to avoid the following error: ``` fatal: couldn't find remote ref refs/heads/v2.0.3-status-v6 error: program 'git' failed with exit code 128 ``` I also had to rewrite some logic in `nix/scripts/source.sh` in order to take account of single-user and multi-user installations. Resolves: #12832 Issue: NixOS/nix#5291 Signed-off-by: Jakub Sokołowski <[email protected]>
