Subject: [PATCH] fix(gateway): update DoH resolver for .eth

Cloudflare decomissionned their resolver and started redirecting
(HTTP 308) to https://dns.eth.link/dns-query which is an alias for
eth.limo.

We change default to https://dns.eth.limo/dns-query
to avoid redirects and cache splitting.

Closes #771
