Tests: Restore entity action module coverage annotations.

Add the two `@covers` annotations omitted when landing [64575], identifying `wp_get_all_registered_entity_action_modules()` and `WP_Entity_Actions_Registry::get_all_registered_action_modules()` as covered by the tests.

Follow-up to [64575].
