Support UriPrefixes with wildcard

[mayafit]

Bug Report

using OpenTelemetry.Exporter.Prometheus.HttpListener version 1.5.0-alpha.1
with .net 7.0

Symptom

I would like to use a wildcard when defining the URIPrefixes . i am doing so using the following code :

        using MeterProvider meterProvider = Sdk.CreateMeterProviderBuilder()
                .AddMeter("MyAppMeter")
                .AddPrometheusHttpListener(opt =>
                {
                  opt.UriPrefixes = new string[] { "http://*:5000/" };
                })
                .Build();

What is the expected behavior?

I would expect the endpoint to be available on port 5000

What is the actual behavior? the endpoint is down

@Yun-Ting Do you recall if this was addressed?

Running into the same issue, tried using the workaround suggested for the older SDK version but it does not seem to pick up and expose the endpoint: https://github.com/open-telemetry/opentelemetry-dotnet/issues/2840#issuecomment-1072977042
