internal/nix: support older nix versions in DaemonVersion

[gcurtis]

To check if nix daemon is running, Devbox runs:

nix store info --json --store daemon

This fails on older versions of Nix for a couple reasons:

• Before Nix 2.19.0, nix store info was nix store ping.
• Before Nix 2.14.0, the --json flag wasn't supported.

Check for both of these versions when constructing the nix store command so it works for Nix versions 2.12 - 2.21+.

Also add a nix.VersionInfo.AtLeast method and constants to make checking for supported major Nix versions easier.

Tested by running the nix store commands on all supported Nix versions.
