Change SPI pins for picow_tcp_server example

[SeyranGrig]

please tell me how to change the SPI pins for connecting the ethernet module W5500. And how set IP address for TCP v.4

This question would be better asked on the pico-examples repository, as that contains the actual example code. However, you would need to change more than just the SPI pins to use a W5500 Ethernet module instead of the Pico W's CYW43439 module, as it will require a different library.
