nixos-unstable release doesn't include `nixos-install-tools` package

[azahi]

To reproduce (as per documentation):

This doesn't allow running nixos-install.

curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-noninteractive-x86_64-linux.tar.gz | tar -xzf- -C /root
/root/kexec/run

This does:

curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-23.11/nixos-kexec-installer-noninteractive-x86_64-linux.tar.gz | tar -xzf- -C /root
/root/kexec/run

Using nixos-anywhere on the nixos-unstable image fails with:

workaround: after nixos-anywhere errors out, you can ssh into the machine and nix-channel --update && nix-env --install nixos-install-tools, then re-run the nixos-anywhere command.
