server.NewServer use http2 some bug

[doraHope]

Describe the bug
i use http2 protocol start a server. but i meet some wrong.
#1 response miss content-length
#2 server conn will close before reply response when get a data frame with end flag.
#3 some bad code.
example:
func: server.rpcServer.ServeConn:
/**
go func(id string, psock *socket.Socket) {
wg.Add(1)
// add to the waitgroup
......
}
*/

To Reproduce
Server Start Code:
/**
func main() {
cert, err := tls.LoadX509KeyPair(<pub>, <key>)
if err != nil {
log.Printf(key pair failed, error %v, err)
return
}
srv := server.NewServer(server.Name(testABC), server.Transport(transport.NewTransport(transport.TLSConfig(&tls.Config{
InsecureSkipVerify: true,
Certificates: []tls.Certificate{cert},
NextProtos: []string{h2, http/1.1},
}), transport.Secure(true))))
srv.Init(server.Wait(nil))
err = srv.Handle(srv.NewHandler(&HelloServer{}))
if err != nil {
log.Printf("new handler failed, error %v", err)
return
}
err = srv.Start()
if err != nil {
log.Printf("go-micro start failed")
}

ch := make(chan os.Signal, 1)
signal.Notify(ch, syscall.SIGTERM, syscall.SIGINT, syscall.SIGQUIT)

select {
// wait on kill signal
case <-ch:
// wait on context cancel
case <-srv.Options().Context.Done():

}

srv.Stop()

}
*/

request server example:

curl request:
curl --http2 --keepalive-time 60 --cacert -iv -H 'Content-Type: application/json'
-H 'Micro-Service: HelloServer'
-H 'Micro-Method: Call'
-H 'Micro-Endpoint: HelloServer.Call'
--data-raw '{}'
-H 'Connection: keep-alive'
https://addr/

curl response:

• Connection state changed (MAX_CONCURRENT_STREAMS == 250)!
  < HTTP/2 200
  HTTP/2 200
  < content-type: application/json
  content-type: application/json
  < date: Sun, 02 Apr 2023 08:47:55 GMT
  date: Sun, 02 Apr 2023 08:47:55 GMT

<
{"A":"hello world"}

• Connection #0 to host dc.com left intact

Expected behavior
#1 when receive frame data with end flag, close conn after reply response.
#2 bad code, may cause response can not reply.
#3 http2 response header should have 'Content-Length'.
