`wp add cpt --name="Instagram posts"` - whitespace in name results in wrong content generation

[KubaDrx]

When using a whitespace within the CPT name, script generates wrong file name and content.

File name generated: Instagram-posts.php (will not autopload in Composer 2.0)

File contents:

<?php

namespace Juniper\Cpt;

class Instagram - posts {
	public string $cpt_slug;
	public string $cpt_name;

	public function __construct() {
		$this->cpt_slug = substr( 'instagram-posts', 0, 20 );
		$this->cpt_name = substr( 'Instagram posts', 0, 20 );

		add_action( 'init', array( $this, 'register_custom_cpt' ) );
	}

class name is wrong.

Also, this is creating another bug within the inc/include.php file:

$juniper_instagram - posts = new \Juniper\Cpt\Instagram() - posts();

Expected behaviour: script should detect whitespaces within the --name param and convert it correctly. Here it should give InstagramPosts.php filename and InstagramPosts class name
