 Ticket #40096 introduced a new change to the return value of
 `get_post_thumbnail_id()` to now always return an int rather than an empty
 string if the post is valid. The function documentation is now inaccurate
 because the `@return` statement was not updated correctly. In turn, this
 means the official API documentation is now also inaccurate.

 It currently says

 `@return int|string Post thumbnail ID or empty string if the post does not
 exist.`

 It should read

 `@return int|string Post thumbnail ID if found, 0 if the thumbnail image
 is not set, or empty string if the post does not exist.`
