[fix] Update censurfridns ipv6 #727
Previous Unicast IPV6 for censurfridns,dk was out of date
One of the ip listed in the resolv.dnsmasq.conf was dead
I've replaced the IP by the right one taken from https://blog.uncensoreddns.org/
Tested the IP on my yunohost instance and it respond properly
How to test
Ping the old IP, it's dead, ping the new one, it answer.
