Manual reference to non existent module (gnu home services ssh-agent)

[Alexandros Prekates]

In https://guix.gnu.org/en/manual/devel/en/html_node/Secure-Shell.html
it says: 

 With the (gnu home services ssh-agent) service, you can configure the
 OpenSSH ssh-agent to run upon login.

But there is no such module.

Alexandros.
