Two-scanner-setup missing RViz config

Steps to reproduce

roslaunch psen_scan_v2_tutorials two_scanners.launch

Expected behavior

In RViz on the left two LaserScan areas are displayed.

Observed behavior

Only laser_1/scan is displayed.

The tutorial states "Rviz will only show a single scanner. To add a second scanner to the visualization you need to add a LaserScan Object to Rviz and then choose "laser_2/scan" as it's topic." - in my opinion the github package should show the package status at the end of the tutorial.
