Add a missing linefeed with a println.

[jmwanderer]

There is a very minor issue in the ScanNetworks example.
A linefeed for networks with the encryption type WPA3.
This results in the following output:

Scanning available networks...
** Scan Networks **
number of available networks:7

0) Aloha Signal: -53 dBm Encryption: WPA2
1) Coral Signal: -67 dBm Encryption: WPA2
2) Attwifi Signal: -75 dBm Encryption: WPA2
3) Zambo Signal: -86 dBm Encryption: WPA34) weiyi Signal: -88 dBm Encryption: WPA2
5) weiyi-guest Signal: -89 dBm Encryption: WPA2
6) 2WIRE049 Signal: -92 dBm Encryption: WPA2

Changing the print to println for WPA3 fixes the issue:

Scanning available networks...
** Scan Networks **
number of available networks:7

0) Aloha Signal: -53 dBm Encryption: WPA2
1) Coral Signal: -67 dBm Encryption: WPA2
2) Attwifi Signal: -75 dBm Encryption: WPA2
3) Zambo Signal: -86 dBm Encryption: WPA3
4) weiyi Signal: -88 dBm Encryption: WPA2
5) weiyi-guest Signal: -89 dBm Encryption: WPA2
6) 2WIRE049 Signal: -92 dBm Encryption: WPA2
