Offer nixos-enter after nixos-install as Per https://nixos.wiki/wiki/Change_root

After one has installed NixOS as per the instructions at: https://nixos.org/manual/nixos/stable/index.html#sec-installation
consider prompting the user and offering to perform nixos-enter to chroot into /mnt.

This can allow the new user to explore their new installation before reboot; but it also teaches them how they might later
use the nix-enter command for rescue perposes.

Of course getting value of this is in providing enough information in the prompt to inform the user of the option,
offer them more info, and showing them what it's doing (much as the web page is already doing; but presented there
