[arch-dev-public] Dropping dingo from [community]

Hi All, I have removed dingo the Google DNS-over-HTTPS client from [community]. The upstream is inactive for years and supports Google only. I would recommend dns-over-https [1] instead which has support for multiple protocols and is still actively maintained. Note that Google announced [2] yesterday that they recommend to use the newer IETF protocol (at a new endpoint), which is also the protocol of all other major DoH providers (CloudFlare, Quad9, etc).
