`--recreate-lock-file` is deprecated

On the "Updating the System" page, this command is given: ``` sudo nixos-rebuild switch --recreate-lock-file --flake . ``` If I run this, I get a warning: > warning: '--recreate-lock-file' is deprecated and will be removed in a future version; use 'nix flake update' instead. I don't know if that means that it's no longer possible to update the system in one command, but you always need two.
