DoH provider list

Thanks for flagging this, Noel! I checked with the team and was able to confirm this is expected. 

Due to a performance issue recently discovered with DNS-over-HTTPS, we have temporarily turned off the built-in list of providers and the auto-upgrade logic that looks at your OS’s DNS setting. Manually providing a resolver URL is still supported.

Here’s some examples of provider URLs that will work if you specify it as a custom provider:

• https://chrome.cloudflare-dns.com/dns-query
• https://doh.xfinity.com/dns-query{?dns}
• https://dns.google/dns-query{?dns}
• https://dns11.quad9.net/dns-query

We will re-enable auto-upgrades and the predefined list of providers after we have resolved the underlying performance issue.
