Zephyr Version / PR for CAN-FD transport

I have written an implementation for CAN-FD transport for Zephyr, since the Agent already supports it.
And it is working very well. Significantly better than USB-CDC and UART for what I have personally tested. I would be happy to submit a PR for it. However, I wrote using Zephyr 3.5, and this module is officially only supported for 2.7.5 and 3.1. The CAN api changed slightly on 3.3, only the frame and filter structs , I think, thus my implementation won't work right away. I don't have problems modifying in to work with 3.1. However, I would like to know from the maintainers, what is the roadmap with respect to Zephyr versions and microROS distros , because 3.1 is quite old now, and EOL. Will rolling be updated to the latest Zephyr version (3.6 at this moment ) ?. That way , I will just submit my current implementation and we can backport it to Humble and Iron. Otherwise, I will submit the PR for 3.1. I would just like to get some feedback about what would the maintainers prefer.

Start by reviewing the existing Zephyr transport support and the CAN-FD implementation referenced in the issue, then confirm which Zephyr versions and micro-ROS distros are supported. A contribution would be complete when maintainers choose the target version and the implementation is adapted for that supported API, with validation against the relevant transport behavior.
