### Description

I am running the latest AGH Edge version on RPi OS (Bullseye 64bit, Linux Kernel 6.1) and notice that DNS-over-HTTPS/3 is reported as DNS-over-HTTPS/2 in query stats logs. For example, domains resolved via "h3://94.140.14.14/dns-query" are reported as domains resolved via "https://94.140.14.14/dns-query". I know both are HTTPS, but I think the stats log should specify whether DNS-over-HTTPS/3 or DNS-over-HTTPS/2 was used. I did verify that DNS-over-HTTPS/3 was resolving via UDP port 443, which means DNS-over-HTTPS/3 works, but is simply reported as DNS-over-HTTPS/2.
