code line does not match the official tutorial

[peterwarlg]

with the Fibonacci.action file defined in official action tutorial as:

# Request
---
# Result
---
# Feedback

Code here should be modified to auto & sequence = feedback->partial_sequence;, otherwise it cannot be compiled successfully

Sigh. This whole thing is confusing because we have Fibonacci.action defined three times:

• https://github.com/ros2/test_interface_files/blob/rolling/action/Fibonacci.action
• https://github.com/ros2/example_interfaces/blob/rolling/action/Fibonacci.action
• https://github.com/ros2/demos/blob/rolling/action_tutorials/action_tutorials_interfaces/action/Fibonacci.action

That said, if you follow the tutorial from https://docs.ros.org/en/humble/Tutorials/Intermediate/Creating-an-Action.html#defining-an-action to https://docs.ros.org/en/humble/Tutorials/Intermediate/Writing-an-Action-Server-Client/Cpp.html, it should do the right thing.

The action here is really to remove two of those three definitions of Fibonacci we have in the code; there is really no reason for three copies.
