Fixes wrong command

🦟 Bug fix

Fixes a typo that happens to be a wrong command in the README

Summary

It happens that the 2nd command the readme shows is
ros2 launch andino_gz andino_gz.launch.py ros_bridge:=false rviz:=false
Note how both arguments are in lower case. That's not an issue for the ros_bridge argument but it is for rviz see the screenshot below.

I didn't dig too deep but it seems when doing the list comprehension to call PythonExpression it expects False (as a valid python boolean) instead of false which is happening here and there

In the other hand ros_bridge is only used with IfCondition, here.
Nevertheless to maintain consistency and avoid having to set one argument in lower case and the other in upper case I changed both since IfCondition works both ways.

I can keep the changes only up to rviz arg if you prefer it.

• Updated documentation (as needed)
