pilz_industrial_motion_planner: Use tf2::fromMsg instead of tf2::convert (backport #3219)

[mergify]

Description

I was compiling pilz_industrial_motion_planner on Windows, and I was obtaining a strange template error:

D:/src/testpilz/ros-humble/output/bld/rattler-build_ros-humble-pilz-industrial-motion-planner_1736462231/h_env/Library/include/tf2\tf2/impl/convert.hpp(60,1): error C2668
: 'tf2::fromMsg': ambiguous call to overloaded function [C:\Users\straversaro\build\trajectory_generation_common.vcxproj]

This specific problems is probably actually a geometry2 problem (see ros/geometry2#444 for a fix on the ROS 1 repo, and ros2/geometry2#369 (comment) that indicates that the issue is still present in the ROS 2 repo.

However, by checking the codebase I noticed that the tf2::convert templated function is only used here (see https://github.com/search?q=repo%3Amoveit%2Fmoveit2+convert%3C&type=code), while tf2::fromMsg is much more used (see https://github.com/search?q=repo%3Amoveit%2Fmoveit2+fromMsg&type=code), so I think that for consistency it make sense to use tf2::fromMsg also in pilz_industrial_motion_planner .
