Wraps the ingestion loop in IngestAudienceMembers with START_EXCLUDE tags so the extracted documentation snippet renders a balanced try-with-resources block.

With this change, the create_client region tag will render in documentation with ... in the excluded region, like this:

// Creates a client for the ingestion service. Increases the maximum metadata size to 16MB to
// prevent RESOURCE_EXHAUSTED errors when responses contain large error details.
InstantiatingGrpcChannelProvider provider =
    IngestionServiceSettings.defaultGrpcTransportProviderBuilder()
        .setMaxInboundMetadataSize(16 * 1024 * 1024)
        .build();
IngestionServiceSettings settings =
    IngestionServiceSettings.newBuilder().setTransportChannelProvider(provider).build();
try (IngestionServiceClient ingestionServiceClient = IngestionServiceClient.create(settings)) {
  // ...
}
