`ros2-distro-mutex` is not aligned on recommended ubuntu distro libraries?

I am trying out pixi with ROS, and I am running into several issues when building ROS packages because ros2-distro-mutex pulls in much newer library versions than those typically used in native ROS setups.

For example, the recommended distribution for humble is Ubuntu 22.04, where the available libpcl-dev version is 1.12.1. However, ros2-distro-mutex pulls PCL 1.15.1. The same situation applies to the other pinned libraries.

This feels like it introduces unnecessary friction for people trying to build ROS 2 with pixi+robostack. Is there a specific reason for this choice?

首先检查 ros2-distro-mutex 的依赖版本锁定，并将其与 ROS Humble 使用的 Ubuntu 22.04 库进行比较，尤其是 PCL 1.12.1 与 1.15.1 之间的差异。确定这些版本锁定是否应与推荐的 ROS 发行版保持一致，或者是否应记录其依据；当不一致得到解决或得到明确解释时，即视为完成。
