mosquitto settings need adaptions

[JonasGhost]

I had an issue with flashing a device because mosquito did not work.
With a configuration file with those settings it did work:
bind_address 0.0.0.0
allow_anonymous true

Bevor that, it did not bind to the wifi interface and did not allow anonymous login.
on mosquitto version 2.0.11, DietPi v8.2.2
