This is similar to #771 but at the time of writing this all UD DoH resolvers seem to be down, breaking DNSLink websites loaded via boxo/gateway if the domain name uses the .crypto TLD.

Current implicit default is Cloudflare at https://resolver.cloudflare-eth.com/dns-query and it stopped returning DNSLink results earlier today (filled support ticket to CF).

The "official" DoH at https://resolver.unstoppable.io/dns-query just hangs and timeouts.

I guess we wait for Cloudflare fix, but if that does not start working we need to consider altenatives (are there any? removal?)

Update: see #772 (comment)
