Fix/classify post action

[mustafauysal]

Description of the Change

These changes address 2 issues with CPT.

1. Don't show the "Classify" action when the post_type is not supported. (post_row_actions, page_row_actions could allow to shown classify action on unregistered post type)
2. Pass post_type for individual classify action. (eg: when you enable classify for the "page" and click on the row item, it doesn't work due to missing post_type on request.

Alternate Designs

Benefits

Making ClassifAI work better in admin UI.

Possible Drawbacks

Haven't seen any drawback, changes are relatively small.

Verification Process

1. Register CPT:

function setup_test_post_type() {
	$args = array(
		'public' => true,
		'label'  => esc_html__( 'FooBar', 'foobar' ),
	);
	register_post_type( 'foobar', $args );
}

add_action( 'init', 'setup_test_post_type' );

2. Enable ClassifAI for foobar only
3. Click to "Classify" action on /wp-admin/edit.php?post_type=foobar for a post
4. See "Classified 1 post." message.

@mustafauysal thank you for this update. Please fix the code regarding the post_type argument or explain the necessity of it.

[cadic]

Looks redundant, the hook handle_bulk_actions-edit-$post_type works regardless of post_type query argument presence.

[mustafauysal]

@cadic It's not redundant but it can be a bit tricky to realize how it hooked on a single classification request at first glance.

In order to see reproduce the issue, please enable classify for "page" post type only, and click on the "Classify" row action for any given page. You will see nothing happens without passing the correct post_type.

wp-admin/edit.php needs to know $post_type to execute the dynamic hook ("handle_bulk_actions-edit-$post_type") accordingly.

I hope this makes sense.

@mustafauysal thank you, I can confirm the action link doesn't work without post_type
