No license in the docs repo

Description

This repository doesn't seem to have a license in it. The ROS2 docs are CC-BY, so I expect this is the license that'll be used for the Gazebo docs as well?

Hey there, team. Happy to send over a PR to add a license to the repo, if you'd like.

Yes, we should use CC-BY as the ROS 2 docs. A PR would be much appreciated!
