Wrong command in readme

[RobertZickler]

Hey everyone,
first of all: thanks for the package. Nice work.
But going through the readme I think there is a mistake
Following
Finally launch the application by:
roslaunch realsense2_description view_d435_model.launch
results in a launch of RViz but no Gazebo. And not
When everything ends, you must see gazebo and rviz loaded and the intel realsense d435 camera with an empty world.

So I think it should be
roslaunch realsense2_description view_d435_model_rviz_gazebo.launch
which results in the desired behavior.

Cheers
Robert
