 We can improve this function by adding a new argument to include
 unregistered post types. This will allow developers to include
 unregistered post types in the query. The new argument is called
 `unregistered_post` and is set to `false` by default. If set to `true`,
 the function will return an empty array if the post type is unregistered.
