v1.8.14-4 to fix bugs

### Releases v1.8.14-4

1. Fix bugs by using some unmerged PRs from original WiFiNINA, such as:

 - [WiFi.config - setting defaults as the Ethernet library #219](arduino-libraries/WiFiNINA#219)
 - [Fix WiFiClient watchdog usage #211](arduino-libraries/WiFiNINA#211)
 - [Watchdog trigger changes #208](arduino-libraries/WiFiNINA#208)
 - [added server.accept() #204](arduino-libraries/WiFiNINA#204)
 - [Fix PinStatus error on some platforms #185](arduino-libraries/WiFiNINA#185)
 
2. Add many WiFiMulti-related examples in [WiFiMulti](https://github.com/khoih-prog/WiFiNINA_Generic/tree/master/examples/WiFiMulti)
3. Update examples
4. Update `Packages' Patches`

+  Advanced WiFi Chat Server
+
+  A more advanced server that distributes any incoming messages
+  to all connected clients but the client the message comes from.
+  To use, telnet to your device's IP address and type.
+  You can see the client's input in the serial monitor as well.
+
+  Circuit:
+    Board with NINA module (Arduino MKR WiFi 1010, MKR VIDOR 4000 and UNO WiFi Rev.2)
+
+  Based on and modified from WiFiNINA library https://www.arduino.cc/en/Reference/WiFiNINA
+  to support nRF52, SAMD21/SAMD51, STM32F/L/H/G/WB/MP1, Teensy, etc. boards besides Nano-33 IoT, MKRWIFI1010, MKRVIDOR400, etc.
