IPAddress has not been declared

Hello,

Since version 4.4.4 compilation failed if WiFiNINA.h is included in the sketch.
Code to reproduce the error :

#include "WiFiNINA.h"

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Error message

WARNING: library WiFiNINA claims to run on samd, mbed_rp2040, megaavr architecture(s) and may be incompatible with your current board which runs on rp2040 architecture(s).

exit status 1

Compilation error: exit status 1

The issue most probably come from commit c79e543

The sketch compiles with version 4.4.3

Does the arduino-libraries/WiFiNINA#281 PR solve the problem? This core also uses ArduinoCore-API as its base.

I suspect the root cause is the above commit removes using arduino::IPAddress;
