Description

This is a fix for few syntex errors and also an update for the example according to the latest documentation.

Working environment:

CircuitPython version: 9.2.4

Target platform

Arduino Nano RP2040 Connect

Line 49:

The ap is a Network object which is not in dictionay type, so the content should be retrieved by obj.attribute_name

Line 58:

The esp object has no dictionary keys named ssid and rssi, but which are packed in the ap_info object according to the official documentation: adafruit_esp32spi - ap_info

Thanks for fixing these! This obsolete code was fixed elsewhere, but I didn't know there was a separate example for the Nano RP2040 Connect.
