Thank you for this tool, it is very useful!

I noticed a deprecation notice that might be incorrect.

sanitize_url() has been deprecated since WordPress version 2.8.0. Use esc_url_raw() instead.

According to the documentation it was restored (un-deprecated) in version 5.9.

https://developer.wordpress.org/reference/functions/sanitize_url/

In: DeprecatedFunctionsSniff.php

    'sanitize_url' => array(
        'alt'     => 'esc_url_raw()',
        'version' => '2.8.0',
    ),

Thanks!
