The structure of ytplayer.config has changed, and it can no longer be explicitly obtained from the webpage. So the function _get_ytplayer_config used for getting automatic captions is no longer valid.

In the latest format of youtube webpage, the url of auto-captions is explicitly stored in ytInitialPlayerResponse, which is exactly the parameter player_response we pass in the edited function _get_automatic_captions. And the original code can handle such structures.
