Description

In tests/phpunit/tests/user/getTheAuthorPosts.php, register_post_type() is used in test_get_the_author_posts_with_custom_post_type() to register a custom post type 'wptests_pt'.

While the test calls _unregister_post_type() inline at the end of the method, an assertion failure before that point leaves 'wptests_pt' registered in the global $wp_post_types array, leaking state into subsequent tests.

This PR adds a tear_down() method in Tests_User_GetTheAuthorPosts to unregister 'wptests_pt' using unregister_post_type(), ensuring complete test isolation.
