moveit2 package must be cloned from the specific branch (foxy)

[oorrppp2]

When I tried followings and did colcon build,

$ cd ~/ros2_ws/src
$ git clone https://github.com/ros-planning/moveit2
$ git clone -b ros2 --single-branch https://github.com/ros-planning/warehouse_ros
$ git clone -b ros2 --single-branch  https://github.com/ros-planning/warehouse_ros_mongo
$ git clone -b ros2 --single-branch https://github.com/ros-planning/srdfdom
$ git clone -b ros2 --single-branch https://github.com/ros-planning/geometric_shapes
$ git clone -b use_new_joint_handle https://github.com/ShotaAk/fake_joint

I met following errors.

I tried

$ git clone -b foxy --single-branch https://github.com/ros-planning/moveit2

instead of

$ git clone https://github.com/ros-planning/moveit2

then the errors were fixed.

If this package runs on ros2 foxy, I suggest you revise that line in README.md.
