update gazebo_ros_pkgs to crystal

[YueErro]

Same as image common, it seems to fail under ros2.

+1, with current ros2 branch the compilation fails with:

--- stderr: gazebo_ros

Let me know what you need. I can take care of this.

Not related to this PR. But since we are changing the gazebo_ros_pkgs branch, can we start using :

  gazebo_ros_pkgs:
    type: git
    url: https://github.com/acutronicrobotics/gazebo_ros_pkgs
    version: ros2_gym-gazebo

This branch contains crystal + some extra plugins not available in the crystal branch yet.
Ill try to make a PR with the ai changes today.
