21640	Incorrect datatype for $post_type param in PHPDocs for count_many_users_posts	willmot	ryan	"`count_many_users_posts` has supported passing the post_type as a second param since #17220 [17742] however the `@param` PHPDocs for the `$post_type` parameter incorrectly list the datatype as `string|array` when in-fact it should be `string`.

Passing an array causes a PHP error because the `$post_type` param is passed to `get_posts_by_author_sql` which assumes it is a string.

Attached patch sets the PHPDocs `@param` datatype for the post_type param to string."	enhancement	closed	normal	3.5	Inline Docs	3.2	normal	fixed	has-patch commit
