Updates to Milan, Eygelshoven, Hong Kong

The resolver in Milan has been moved to a new server and a new provider. I am migrating away from Virtono since they decided to send AI-generated responses to support tickets instead of dealing with the actual issue. Therefore, its IP addresses have changed.

A third resolver in Hong Kong has been added as well as a resolver in Eygelshoven, Netherlands. Both are sponsored by MLNL.HOST. Many thanks to them for their support!
