This PR unregisters the taco custom post type registered during Tests_Post_wpListPages::test_wp_list_pages_classes_with_hierarchical_cpt() in tear_down() using the public unregister_post_type() function, preventing fixture leakage and replacing the internal mid-test call.

Thanks @devmuhib009!

Properly unregisters the taco custom post type in tear_down() and removes the mid-test unregistration call in Tests_Post_wpListPages, preventing fixture leakage across tests. Looks good to me!

What changed in this PR

This PR improves fixture cleanup in Tests_Post_wpListPages by moving custom post type removal into the test teardown lifecycle.

Changes:

• Adds tear_down() to unregister taco using the public unregister_post_type() API before calling the parent teardown.
• Removes the internal mid-test cleanup call so cleanup still runs if an assertion fails.
