bug: all "Unstoppable Domains" (.crypto) DoH resolvers are down

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?)

How does DoH story look like for UD? Should we keep defaulting to Cloudflare (assuming its fixed soon)?
We would prefer using https://resolver.unstoppable.io/dns-query directly, but it seems to be offline.

I'm testing with:

$ curl 'https://resolver.unstoppable.io/dns-query?name=_dnslink.test.crypto&type=TXT' -H 'accept: application/dns-json' -v
* Host resolver.unstoppable.io:443 was resolved.
* IPv6: (none)
* IPv4: 3.33.139.32
*   Trying 3.33.139.32:443...
* ALPN: curl offers h2,http/1.1
* TLSv1.3 (OUT), TLS handshake, Client hello (1):

and just hangs.

Team is on holiday, but we would like to resolve this in January (either fix .crypto, or remove default resolver.cloudflare-eth.com if not fixed by then)
