CLI/config: simulate top level comments when creating config

According to discussion on

          https://gitlab.gnome.org/GNOME/glib/-/issues/3078

it looks like upstream will stop supporting top of file comments.

It is questionable whether we really need this feature, but for now
update notmuch-config to simulate it.
