Use console_direct event handler for colcon test

[christophebedard]

action-ros-ci currently uses console_cohesion+ for both colcon build and colcon test. ci.ros2.org uses console_cohesion+ for colcon build (prints output once package is done being processed) and console_direct+ for colcon test (prints output directly).

Users can override the default event handler selected by action-ros-ci using the extra-colcon-args input (since those extra args are added on to the end of the colcon test call, and CLI arguments override any previous argument), but I think it makes sense to change the default event handler for colcon test to console_direct+.
