Update wpa_supplicant Instructions for Bookworm

[mbaker3]

Is your feature request related to a problem?

On RaspOS bookworm based installations wpa_supplicant doesn't appear to be respected or at least conflicts with more modern ways of setting the preferred wifi network and auto connect settings.

While trying to setup my RaspAP instance the system kept auto connecting to a wifi network that wasn't the one in my wpa_supplicant.config. Strangely, if the supplicant network was available it would connect to that network but keep the gateway IP from the "preferred network" configured in nmtui. If the network in wpa_supplicant.config wasn't available then the system would auto connect to the network configured in nmtui

I ran nmtui and changed my preferred network to the network I'd like and then removed the @reboot command from cron and my system works as expected.

Describe the solution you'd like

Update the FAQ documentation to mention that RaspOS Bookworm installations should manage their preferred WiFi network through the nmtui command.

Describe alternatives you've considered

Provide workarounds to prevent nmtui from affecting the preferences selected in the wpa_supplicant.config
