The error is coming from an older version of pytest. You have pytest v4.6.9 installed. However, colcon is expecting to have the pytest version equal to or higher than 5.3. On my Ubuntu 20.04, I have pytest v7.1.1. I am not sure, but did you install the ROS properly? You may try upgrading pytest manually, though.
