Missing declaration in WiFiNINA and WiFi library reference example code

[aster94]

hello,

i was looking the wifi reference and found a little error in the bssid page there is a missing declaration of status, not very important but i thought to open it anyway in case it creates any headache to newcomers

Edit: same in the wifinina page: https://www.arduino.cc/en/Reference/WiFiNINABSSID
