ci: upgrade Nix from 2.3.12 to 2.6.1
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.
We default to multi-user for Darwin, but not for any other OS due to
discovered issues with `nix-daemon` socket on Arch and open file limits.

I also rewrote `nix/scripts/setup.sh` and `/nix/scripts/purge.sh` to support
different types of installations. Both single-user and multi-user, as some
operating systems have issues with multi-user installations.

Resolves: https://github.com/status-im/status-react/issues/12832
Depends on: https://github.com/status-im/status-jenkins-lib/pull/37
