Describe the feature you'd like

Hi there,

I've been trying out the Helidon SE backend framework and was hoping that there might be some automatic support for its tracing framework in dd-trace-java.

I see that Helidon has first-class support for OpenTelemetry, which is an option: https://helidon.io/docs/v4/se/telemetry/open-telemetry - but for backend frameworks like Dropwizard or Spring I valued the simplicity of being able to add the Datadog tracer and not do too much configuration or set up additional collectors.

I see that there are potentially good hooking points provided by io.helidon.tracing:helidon-tracing.

I used the GitHub search tool to look for "Helidon" keywords in this repo but couldn't see anything open/closed, so thought I'd open a request for your consideration.

Adding these dependencies doesn't appear to be enough to capture any APM traces, with the Helidon defaults (i.e. no configuration) currently:

    implementation(platform("io.helidon:helidon-dependencies:4.2.0"))
    ...
    implementation("io.helidon.tracing:helidon-tracing")
    implementation("io.helidon.tracing.providers:helidon-tracing-providers-opentelemetry")
    implementation("io.helidon.webserver.observe:helidon-webserver-observe-tracing")

Thanks,
Sage
