PHP implicitly nullable deprecations in Exception-Classes

[mx-jhinz]

Hey, we are using PHP 8.4 and the current version v7.x receive deprecations in the src/Exception/* folder in the Exception-Classes.

For example in class:

src/Exception/InvalidRequiredArgumentException.php
src/Exception/InvalidOptionalArgumentException.php

The used __construct functions are using old style of defining nullable parameters. As of PHP 8.4 this will throw a Deprecation: implicitly nullable parameters require it explicitily in the type def.

Current code with deprecation

public function __construct($message, $code = 0, Exception $previous = null)
//                                               ^^^^^^^^^ Implicitly marking parameter as nullable is deprecated 
{
    parent::__construct($message, $code, $previous);
}

Fixed code with PHP ^8.2 style

public function __construct($message, $code = 0, ?Exception $previous = null)
//                                               ^
{
    parent::__construct($message, $code, $previous);
}

Could you please fix all occurrences to avoid deprecations in PHP 8.4 projects? Thanks.
