Issue with RosPublisherSystem in Python

[phanikiran1169]

Hello,

On the latest commit f208880 for drake-ros, there is an issue with the usage of RosPublisherSystem in Python. I am unable to run the example python script rs_flip_flop.py

Details

OS: Ubuntu LTS 22.04 LTS
ROS Distribution: Iron
Drake (installed via APT): drake-dev 1.37.0-1

Error Log

sirhawk@phani:~/test/src/drake-ros$ ros2 run drake_ros_examples rs_flip_flop.py
Traceback (most recent call last):
  File "/home/sirhawk/test/install/drake_ros_examples/lib/drake_ros_examples/rs_flip_flop.py", line 152, in <module>
    main()
  File "/home/sirhawk/test/install/drake_ros_examples/lib/drake_ros_examples/rs_flip_flop.py", line 91, in main
    RosPublisherSystem.Make(Bool, "Q", qos, sys_ros_interface.get_ros_interface()))
  File "/home/sirhawk/test/install/drake_ros/lib/python3.10/site-packages/drake_ros/core/__init__.py", line 88, in _make_ros_publisher_system
    return RosPublisherSystem(
RuntimeError: Unable to load a custom holder type from a default-holder instance
cannot publish data, at ./src/rmw_publish.cpp:62 during '__function__'
Fail in delete datareader, at ./src/rmw_service.cpp:100 during '__function__'
[ros2run]: Segmentation fault

The above error is specific to Python. The C++ executable works without any errors. I also noticed that this issue was not present in the commit b6fba61 (This is my current working commit and I have no issues with RosPublisherSystem in Python. I have noticed this issue when I have pulled in the latest commit)

C++ working log

sirhawk@phani:~/test/src/drake-ros$ ros2 run drake_ros_examples rs_flip_flop

Kindly let me know if my observations are valid
