[Docs] Wrong ckpt path for pose_resnet_101 model, input size 384x288, trained on coco dataset

[xymsh]

📚 The doc issue

Please refer to the file configs/body_2d_keypoint/topdown_heatmap/coco/resnet_coco.md. Ckpt path for "pose_resnet_101, 256x192" and "pose_resnet_101, 384x288" are the same. Could you please update the correct ckpt path for pose_resnet_101, 384x288?
