[Improvement] Please indicate that LDS_MODEL variable should be set on both PC and TurtleBot3

[kotokaze]

I recently moved to ROS 2.
I get an error and abort when trying to use LiDAR with turtlebot3_cartographer and others with old TurtleBot3s. However the newer one with LDS-02 works as expected.

Finally, I noticed that the cartographer seems to run with LDS-02 by default. It took me a long time to realize that the environment variable LDS_MODEL=LDS-01 needs to be set on the PC side as well as on the bot itself.

Could you please note to set LDS_MODEL at least when using LDS-01 in the documentation?
