Please describe.**\r\nIn version 1.133.0, java pubsub client already use OpenTelemetry. But after testing it, it does not automatically propagate `baggage` information. It only propagates `traceparent` information.\r\n\r\n**Describe the solution you'd like**\r\nAutomatically propagate baggage information. \r\n\r\n**Describe alternatives you've considered**\r\nAutomatically propagate context using registered propagators in open telemetry.\r\n\r\n**Additional context**\r\nSimilar to how kafka auto instrumentation works, they use `openTelemetry.getPropagators().getTextMapPropagator()` to get the propagators and inject it using `propagator().inject(context, record.headers(), SETTER);`. \r\nhttps://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/e2dd703a8a0d47ed12d3beca79dc9740822da4f1/instrumentation/kafka/kafka-clients/kafka-clients-2.6/library/src/main/java/io/opentelemetry/instrumentation/kafkaclients/v2_6/KafkaTelemetry.java#L226","author":{"url":"https://github.com/mroeha","@type":"Person","name":"mroeha"},"datePublished":"2024-10-24T03:43:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/2242/java-pubsub/issues/2242"}
