work with opentelemetry without "http_route" and "http_url" attribute printed

[charzhao]

I use below code to get metrics with OTel:

.WithMetrics(cfg =>
{
cfg.AddAspNetCoreInstrumentation();
cfg.AddHttpClientInstrumentation();
cfg.AddRuntimeInstrumentation();
});
but in the output i did not get http_route attribute as below:

http_client_request_duration_seconds_bucket{http_request_method="GET",http_response_status_code="200",network_protocol_version="1.1",server_address="****.com",url_scheme="https",le="0.5"} 0 1706514537848

Is there any way to make http_route and http_url here?
