Deprecated function: Creation of dynamic property Drupal\pathauto\AliasCleaner::$punctuationCharacters is deprecated

The change in #2 work great at getting rid of the deprecation error. But it unintentionally causes the list of punctuation characters to be re-generated every time pathauto needs that list (instead of caching it in a array).

I think this is very close to RTBC.

@JohnAlbin agree. I removed
$this->punctuationCharacters = [];

Isn't this issue is duplicate of https://www.drupal.org/project/pathauto/issues/3328670 📌 PHP 8.2 compatibility Fixed

It is. I close this one (the linked was created earlier)
