Creation of dynamic property Nordigen\\NordigenPHP\\API\\RequestHandler::$authentication is deprecated in /home/.../public/vendor/nordigen/nordigen-php/src/API/RequestHandler.php on line 17

[johnyfernandes]

Describe the bug
After updating to PHP 8.3, I started to get this error:
Creation of dynamic property Nordigen\\NordigenPHP\\API\\RequestHandler::$authentication is deprecated in /.../.../public_html/.../public/vendor/nordigen/nordigen-php/src/API/RequestHandler.php on line 17

To Reproduce
Steps to reproduce the behavior:

1. Use the library using PHP 8.3

Expected behavior
I expected it to work, to authenticate properly.

Additional context
The warning is occurring because PHP 8.2 and later versions have deprecated the creation of dynamic properties. To resolve this, we should explicitly declare the $authentication property in the class.
