PX4 v1.13.2 with Ignition Gazebo 6 Simulation

As the old “ignition” (gazebo 5 based) is not retired, and the “gz” (Gazebo garden) is the main simulator, I noticed that PX4 v1.13’s ignition simulation won’t work with current ignition gazebo packages available (v1.14 ~).

So I have left comment in this issue to address this problem:

Key summary is:

  1. Update “simulation-ignition” to use Gazebo6
  2. Remove force to use Gazebo 5 condition in sitl run script
