Changes for PHP 8.1 and Symfony process (5) - Event Dispatcher( 5)

[ARY112]

Is it possible to create a new version for parallel-process.As with Symfony process and Event dispatcher changes, existing will not work for Symfony process and Event dispatcher version are less <5. Creating a new version will help people who want to use PHP 8 and updated Symfony process and Event Dispatcher(>=5.0) and previous version can be used as it is.

Kindly let me know if any more contribution required from my side.
