enable ECH
ECH is available as a beta on Cloudflare, I think we should enable it since F-Droid is all about privacy. This gives us a nice testbed for ECH which we can hopefully roll out on f-droid.org soon. Plus I think there will be some other fringe benefits.

Apparently Cloudflare has disabled it for sites that were configured via the beta program, but it is still on for other sites.
