We use [connect-go](https://github.com/bufbuild/connect-go) instead of [grpc-go](https://github.com/grpc/grpc-go) because connect-go support HTTP/1.1, that means we can mount the gRPC api on the Gitea server without change the protocol.
So it doesn't make sense that make the runner support both HTTP/1.1 and HTTP/2, and [upgrade the protocol used on Gitea](
ae018b6b48/modules/graceful/server_http.go (L23)) to support HTTP/2 and h2c. Although it works right now, I believe there'll be lots of problems when the Gitea server is behind a reverse proxy.
So let's KISS, we don't touch the http protocol of Gitea, and disable HTTP/2 for runner. And we would support HTTP/2 in the future if we really need it.
