AL0089 - Missing OTLP configuration

Configure OTLP endpoint explicitly

builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter()); // default endpoint

Good Code

builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter(o =>
        o.Endpoint = new Uri("https://collector.example.com:4317")));
