Unknown: Creation of dynamic property in PHP 8.2

[MarvinKlein1508]

Dynamic properties have become deprecated in PHP 8.2.
https://php.watch/versions/8.2/dynamic-properties-deprecated

When setting up a local XAMPP with latest main branch you will see tons of warings regarding this.

Unknown: Creation of dynamic property Template\Twig::$data is deprecated in C:\xampp\htdocs\opencart\system\library\template\twig.php

Affected files I've found so far:

• C:\xampp\htdocs\opencart\system\engine\proxy.php

  opencart-3/upload/system/engine/proxy.php

  Line 26 in 98b2ee6

  $this->{$key} = $value;

• C:\xampp\htdocs\opencart\system\library\template\twig.php

  opencart-3/upload/system/library/template/twig.php

  Line 10 in 98b2ee6

  $this->data[$key] = $value;

Tons of warnings. What needs to be known are the routes where you see those dynamic property messages.
