stuebinm 6afb255d97 nixos: remove all uses of lib.mdDoc
these changes were generated with nixq 0.0.2, by running

  nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix

two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.

Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.

Like `system.systemBuilderCommands`, but only for the commands that are
needed *both* when the system is activatable and when it isn't.
Disclaimer: This option might go away in the future. It might be
superseded by separating switch-to-configuration into a separate script
which will make this option superfluous. See
https://github.com/NixOS/nixpkgs/pull/263462#discussion_r1373104845 for
a discussion.

A separate activation script package that's not part of the system profile.
This is useful for configurations where `system.activatable` is `false`.
Otherwise, you can just use `system.build.toplevel`.
