Resolve issue with balena-wifi-connect (former resin-wifi-connect)

[vpetersson]

It appears as we've broken the WiFi configuration somewhere along the upgrade process (either in Bullseye or in the containerization).

Since we're using an old version, the first process would probably be to upgrade it (we're still using resin-wifi-connect rather than balena-wifi-connect). Hopefully that will get us going.

As mentioned by Viktor on Slack, might read up on what raspi-config does when enabling the Wi-Fi.

• Enabling Wi-Fi via raspi-config might introduce side effects.
• Might as well read up on creating a blank ssh file and a wpa_supplicant.conf file to enable Wi-Fi.
