Upgrade Alpine:3.22 avahi to version 0.8-r21 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream avahi package and not the avahi package as distributed by Alpine. See How to fix? for Alpine:3.22 relevant fixed versions and status.

A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs.
