Fix correct usage of angular velocity in update_odometry() function (backport #1118)

[mergify[bot]]

Thanks for this nice steering_controllers_library!

Using it however, we noticed issues in the odometry calculation where our steered robot would spin incredibly fast. There seems a small math error in the calculation which this PR fixes: The integration expects distances and angles, while the accumulators expect a velocity.

Probably also relates to https://github.com/ros-controls/ros2_controllers/issues/937
