Regression on ROS 2 Buildfarm for Rolling

`bwehaviortree_cpp 4.6.2` is failing to build for Rolling on the buildfarm with the error below. This is blocking the [announced Rolling sync](https://discourse.ros.org/t/preparing-for-rolling-sync-2025-04-11/43166). We will proceed with the sync which will remove these binaries from Rolling but they will be added once the build is fixed and a new release is bloomed.
