MINOR: stats: display new curr_sess_idle_conns server counter

Browse Source 
Add a new stats column in proxy stats to display server counter for
private idle connections. This counter has been introduced recently.

The value is displayed on CSV output on the last column before modules.
It is also displayed on HTLM page alongside other idle server counters.

@ -1356,6 +1356,7 @@ Here is the list of static fields using the proxy statistics domain:
111. h3req [.F..]: total number of HTTP/3 sessions processed by this object
since the worker process started
112. proto [L...]: protocol
113. priv_idle_cur [...S]: current number of private idle connections
For all other statistics domains, the presence or the order of the fields are
not guaranteed. In this case, the header line should always be used to parse
