[Docs] Unable to output left and right hand labels for detected hand keypoints

[ccchen091]

📚 The doc issue

When I use mmpose for hand keypoint detection, I do detect the hand keypoint coordinates correctly and output them to a json file, however, I can't output in the json file whether the detected hand keypoints are left-handed or right-handed, how can I fix this problem

Suggest a potential alternative/fix
