Fixes #11820
-Made the Zap as the default ErrorLog Supplied to the Http server

We should return errors as soon as they happen, not later.

Suggested change

	errorLog, err := zap.NewStdLogAt(settings.Logger, zapcore.ErrorLevel)
	errorLog, err := zap.NewStdLogAt(settings.Logger, zapcore.ErrorLevel)
	if err != nil {
	return nil, err
	}

the suggested change was the initial code too
but in
https://github.com/open-telemetry/opentelemetry-collector/pull/11830/files/71c16e0b293b4d6ed25146c4dd295093e672afd7#r1880527497
it was suggested to return server,err so that to avoid coverage report failures.

Then, how about something like:

server := &http.Server{
	Handler:           handler,
	ReadTimeout:       hss.ReadTimeout,
	ReadHeaderTimeout: hss.ReadHeaderTimeout,
	WriteTimeout:      hss.WriteTimeout,
	IdleTimeout:       hss.IdleTimeout,
}

errorLog, err := zap.NewStdLogAt(settings.Logger, zapcore.ErrorLevel)
if err != nil {
	return server, err
}

server.ErrorLog = errorLog
return server, nil

Then, we can handle multiple things that could return errors, and we also keep error return alongside its definition.

I will check the report locally and may be make the change according to it
the command for it is make gotest-with-cover right?
