The semconv.HTTPServer already produces the existing v1.20.0 server metrics (#6002). The following methods need to be updated to produce the new server HTTP metrics:

• RecordMetrics

These updates should ensure that when OTEL_SEMCONV_STABILITY_OPT_IN="http/dup" is set the produced telemetry is compliant with these semantic conventions:

• http.server.request.duration
• http.server.request.body.size
• http.server.response.body.size
