Wrong include file cv_bridge for rviz plugin for ROS2 Jazzy

[kiashik]

realsense-ros/realsense2_rgbd_plugin/src/ros_image_texture.cpp
realsense-ros/realsense2_rgbd_plugin/src/ros_image_texture.cpp

In the above two files, cv_bridge is imported using #include <cv_bridge/cv_bridge.h>. From my understanding, it should be #include <cv_bridge/cv_bridge.hpp>.

If I leave it as is, i.e. #include <cv_bridge/cv_bridge.h> and run this colcon build command colcon build --packages-select realsense2_rviz_plugin --cmake-args -DRVIZ_RGBD_PLUGIN=ON then I get the following error message.

Making this changes resulted in a successful build. I'm running this a laptop with the following specs:

Operating System: Ubuntu 24.04.3 LTS              
Kernel: Linux 6.8.0-100-generic
Architecture: x86-64
Hardware Vendor: Lenovo
Hardware Model: Legion S7 15ACH6
Firmware Version: HACN46WW

I hope this helps! My apologies if this is not an actual issue. Thank you!
