Update maintainers and add url tags (backport #1363)

[mergify]

The contents of the package.xml get parsed for index.ros.org, so I thought it might be worth updating them.

• Update the current maintainers
• Where possible, I added the original authors as <author>
• add url tags, but only to github and control.ros.org homepage. The direct links to the controllers have the ROS distro in the URL, that would soon become outdated.
