Wrong launch file

[mounteverset]

On the page https://docs.clearpathrobotics.com/docs/ros/tutorials/navigation_demos/nav2/ for version ROS 2 Jazzy

in step 4 (both sim and real robot):

4. Start Rviz to view the map by running

ros2 launch clearpath_viz view_navigation namespace:=/a300_0000 use_sim_time:=true

should be changed to

ros2 launch clearpath_viz view_navigation.launch.py namespace:=/a300_0000 use_sim_time:=true

Thanks for catching this! PR #492 will fix it.
