fix(gateway): update DoH resolver for .eth DNSLink (#781)

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 Co-authored-by: Andrew Gillis <[email protected]>
