Description

The description of --ignore-leaf-topics doesn't much the implementation

--ignore-leaf-topics  Ignore topics without a publisher.

The implementation of check function is

rosbag2/rosbag2_transport/src/rosbag2_transport/topic_filter.cpp

Lines 81 to 87 in 65c889e

	bool
	is_leaf_topic(
	const std::string & topic_name, rclcpp::node_interfaces::NodeGraphInterface & node_graph)
	{
	auto subscriptions_info = node_graph.get_subscriptions_info_by_topic(topic_name);
	return subscriptions_info.size() == 0;
	}

So I think the description should be Ignore topics without a subscription

System (please complete the following information)

• OS: Ubuntu Jammy
• ROS 2 Distro: rolling
• Version: rolling branch

OS: Ubuntu Bionic

Should be Jammy? since the issue is detected with rolling?
