Update topic info verbose test for buffer backend output

[nvcyc]

Description

Update the ros2 topic info -v CLI test expectation to include the new buffer backend line emitted in verbose endpoint output.

Is this user-facing behavior change?

Yes. While the change in this pull request is for a test case, the underlying changes in other relevant packages add rosidl buffer backend information for each endpoint in ros2 topic info -v.

Did you use Generative AI?

No.

@mjcarroll Does it make sense to run CI on this, or can we just merge ?

[nvcyc]

@jmachowinski I have CI tests running here which is currently failing. I'm checking and addressing the failures and will update in relevant PRs when passed before we consider merging them all together.

@nvcyc are you using the ros-for-ci scripts ?
You can specify mutiple PRs spanning multiple repos at once, and the script will post the same CI run in all PRs.

Thanks for the hint. Yes, I'm using ros-ci-for-pr --branch nvcyc/buffer_backend_topic_info --pulls ros2/rmw_zenoh#988 --build --colcon-build-args="--continue-on-error" --comment.

I used --branch nvcyc/buffer_backend_topic_info and only made it post the result in one of the PRs (the rmw_zenoh one) to not spam relevant PRs with failed CI run posts while I'm addressing the CI failures. Will copy the results to all the relevant PRs for the records once it's green and ready.
