DNS over HTTPS in Windows 11

Requires Windows 11.

GPO-EnforceDoH.reg enables the group policy to require DoH. However it didn’t seem to work for me or it allowed me to set the DNS server to not use DoH.
DohWellKnownServers adds DoH support for multiple IPv4 & IPv6 addresses that Windows 11 isn’t shipping by default, currently:
- Mullvad
- Mullvad Adblock
- Adguard
- Quad9 ECS (Windows 11 defaults include Quad9 default)
- Cloudflare antimalware
