Update host URL for BraveDNS "free" resolver
It appears that https://free.bravedns.com/dns-query does not resolve but using https://free.bravedns.com or https://basic.bravedns.com. However, testing all 3 using Firefox's built-in resolver work.
Also, the same privacy policy applies to "free" and "basic," however under their configuration page, "basic" is used. So I'll just use that for now.
