Hi,
Now I'm actively working on this repo to migrate to ROS2.
It is done, and I want to change the default branch from ros1 to ros2.
But I have no permission to change the default branch of this repository.
Can anyone help to change it?

I've updated it for you. And I've tried moving the maintainers to have Maintenance access to enable you to hopefully improve the list of things you and the other maintainers can access

@tfoote Thank you so much!
