Create release

[Rick-v-E]

It would be nice to create a release of this repository in ROS, so that we can install it like sudo apt-get install ros-humble-virtual-maize-field.

What we have to do:

• Rename branch names to something that makes more sense, like noetic-devel, foxy-devel, galactic-devel, humble-devel and rolling-devel. We can use the Backport Action to keep all ros2 branches up to date.
• Have some automated tests to check that the generate_world script is not failing for any of the predefined world configs (made start in the ros2 branch but they are failing sometimes).
• Add Github username + email in package.xml.
• Add a source to ros/rosdistro.
• Create a release team in ros2-gbp-github-org.
• Change save location of generated files (Change location of generated files ROS 1 #55, Change location of generated files ROS 2 #56)
