links to pico_w-examples in README.MD are not working #228
Description
For example
https://github.com/raspberrypi/pico-examples/blob/master/pico_w/picow_wifi_scan
gives 404 error
https://github.com/raspberrypi/pico-examples/tree/master/pico_w/wifi_scan
or
https://github.com/raspberrypi/pico-examples/blob/master/pico_w/wifi_scan
both work fine
