nixos/tor: add tor hidden service options (#28081)

* nixos/tor: add hiddenServices option

This change allows to configure hidden services more conveniently.

* nixos/tor: fix default/example mixup

* nixos/tor: use docbook in documentation

Also use more elegant optionalString for optional strings.

* tor: seperate hidden service port by newline

* tor: better example for hidden service path

a path below /var/lib/tor is usually used for hidden services

At a minimum, you should just specify the port for the
relay to listen on; a common one like 143, 22, 80, or 443
