LGTM @Ryanf55 - I've rebuilt microxrceddsgen using this branch and verified that ArduPilot/ardupilot#26095 is building, so should be good to merge.

Is there anything in CI that requires updating before this can be merged?

I'll manually trigger a rebuild in ardupilot_docker for a new image. No code changes should be needed.
