Fix formatting of commented out lines of code

[AdamPettinger]

Description

The Move Group C++ Interface tutorial for Noetic has some of the move/execute lines commented out:

• // move_group_interface.execute(my_plan);
• // move_group_interface.move();

which makes the tutorial formatting add these as plain text and makes the page look weird:

This PR changes those lines so they appear as code that is commented out.

It also comments out an execute call later in the tutorial that gives a "no controllers found" warning if left in

Why should the robot not move? In simulation that shouldn't be a problem.

Why should the robot not move? In simulation that shouldn't be a problem.

Good question... The short answer: because that is how it was before this PR. The longer answer: this tutorial wasn't always planning starting from the end of the previous plan, so some of the plans being executed was causing problems with the starting state and the robot state not being the same.

I reworked the flow of the tutorial a bit to show the execute() and move() methods, and have the sim panda move through some of the plans.
