Gazebo Sim `WindEffects` on X500 model

[JacopoPan]

In the wind.sdf world in gz-sim examples (https://github.com/gazebosim/gz-sim/blob/gz-sim10/examples/worlds/wind.sdf), the tag <enable_wind> is introduced at the link level on each link.

In this repo, it is set in the main link of the ground_plane model only.

However, if I add the tag (set to true) to the base link of an x500 model, it does seem to result in a more intuitive behavior (i.e. hover in a non-zero wind field is tilted against the wind):

  <model name='x500'>


    <pose>0 0 .24 0 0 0</pose>
    <self_collide>false</self_collide>
    <static>false</static>
    <link name="base_link">
      <enable_wind>true</enable_wind>
      <inertial>

Are wind effects otherwise applied via the plugins or only used for state estimation with the appropriate sensors?
