The instructions to change from AP to client mode can be updated (see #105)

[Vincent-Stragier]

Hello,

In issue #105, thanks to @linuxdan, we have seen that the image can be switched from AP to client mode directly using the Pi Imager. It allows to directly configure the Wi-Fi. Note that the user should not change the default username and password, since it will “destroy” the app (maybe something to improve later by making the app user independent).

Using directly the Pi Imager makes this change easier to apply.

Best,
Vincent
