php 8.4 deprecation error - flysystem

[jcogs-design]

Description of the problem
This deprecation error appearing when running EE7.5.17 under php 8.4

Deprecated
: ExpressionEngine\Dependency\League\Flysystem\FileNotFoundException::__construct(): Implicitly marking parameter $previous as nullable is deprecated, the explicit nullable type must be used instead in
/var/www/html/system/ee/vendor-build/expressionengine/flysystem/src/FileNotFoundException.php
on line
19

Environment Details:

• Version: 7.5.17
• PHP Version 8.4.14

Possible Solution
Modify the class constructor declaration thusly:

    public function __construct($path, $code = 0, ?BaseException $previous = null)

Additional context
Probably about time EE upgraded from the deprecated Flysystem 1.1.x to Flysystem 3 ...
