Because remote_connect_back needs the HTTP REMOTE_ADDR header to see
where the request came from. Requests on the CLI don't have HTTP
headers.

It currently says
(https://xdebug.org/docs/all_settings#remote_connect_back):

        If enabled, the xdebug.remote_host setting is ignored and Xdebug
        will try to connect to the client that made the HTTP request. It
        checks the $_SERVER['REMOTE_ADDR'] variable to find out which IP
        address to use.

I have added some text to clarify that it doesn't work with the CLI.
