Removing examples/contact_model (RobotLocomotion#12719)

The examples in contact_model/ were examples of the old RBT contact model.
They don't exercise MBP and its contact models. They *could* be brought
back and updated to MBP if, down the road, we feel they have value.

Note: the default docker behavior was already configured to run the
acrobot, only the documentation mistakenly referred to the bowling
simulation. Now they match.
