raspicam2 package is no longer supported

[ptientho]

camera_node = Node(
      package='raspicam2',
      condition=IfCondition(PythonExpression(['not ', use_sim_time])),
      executable='raspicam2_node',
      name ='pi_camera',
    )

This node launch is from bringup.launch.py. It does not work because raspicam2 is deprecated.

The replacement would be camera_ros
