Tools: Update ardupilot_gazebo install script

[srmainwaring]

Follow up to #22598

• Update prerequisites
• Update workspace and build order.
• Update GZ envs.

Host: macOS Monterey 12.6, Intel Mac Pro
System: Ubuntu Focal 20.04.5 LTS on VMware Fusion 13.0

Testing

1. Run script for package ros-base

./install-ROS-ubuntu.sh -p ros-base

2. Check env variables correctly set in .bashrc

$tail ~/.bashrc

#---------------------------------------------------------
# ArduPilot
export  PATH=$PATH:$HOME/Code/ardupilot/ardupilot/Tools/autotest

source /home/rhys/ardupilot-ws/devel/setup.bash
export GZ_SIM_SYSTEM_PLUGIN_PATH=/home/rhys/ardupilot_gz_ws/src/ardupilot_gazebo/build:
export GZ_SIM_RESOURCE_PATH=/home/rhys/ardupilot_gz_ws/src/ardupilot_gazebo/models:/home/rhys/ardupilot_gz_ws/src/ardupilot_gazebo/worlds:

3. Run the Iris example (in new terminal)

gz sim -v4 -r --render-engine=ogre iris_runway.sdf

(need to use ogre rather than ogre2 if rendering on a 20.04 VM).

@srmainwaring,

Thanks very much for this. Could you rebase on master so the "Merge branch" commit disappears?

[rmackay9]

Merged, thanks!
