Hi Team,

I found couple of issue with the current document.

1. performance_test compilation Failure

--- stderr: performance_test                                   
CMake Error at CMakeLists.txt:437 (message):
  Unsupported ROS_DISTRO

The workaround I attempted and found successful,

export ROS_DISTRO=rolling

2. perf_test failure with rate 0

sudo env PATH="$PATH" LD_LIBRARY_PATH="$LD_LIBRARY_PATH" ./install/performance_test/lib/performance_test/perf_test -c rclcpp-single-threaded-executor -p 1 -s 1 -r 0 -m Array1m --reliability RELIABLE --max-runtime 60 --use-rt-prio 98

[1]    256710 abort      sudo env PATH="$PATH" LD_LIBRARY_PATH="$LD_LIBRARY_PATH"  -c  -p 1 -s 1 -r 0 

It seems that this bug is intermittent. ros2/rclcpp#827

I kept the rate 1 and its working.

3. The bokeh version is incompatible with the callback duration.ipynb module.
In the 3.x bokeh release, the plot_width attribute of a figure was replaced with width. Similarly, plot_height was replaced with height. Its working with 2.4.3 version which is previous release.
