'Goal right post left': 'Goal left post left ',

The pitch annotations of the sn-calibration dataset had 'Goal left post left ', but for the pitch annotations in the sn-gamestate dataset, it changed to 'Goal left post left' (just the space at the end removed). The file plugins/calibration/sn_calibration_baseline/soccerpitch.py has been partially modified to account for this change, but there are still those two lines mentioned at the beginning to adapt to the new annotation. Without this change, the file plugins/calibration/sn_calibration_baseline/evalai_camera.py fails to evaluate the camera calibration on the sn-gamestate dataset and outputs an error message like Incorrect key 'Goal left post left'.
