Hey @kubawerlos, thank you for putting this PR together. Could you do either of these things for me so we can merge this PR in:

• Check the maintainers can edit checkbox
• Squash the commits into one and use the commit message from a6b551a

@WyriHaximus as I make a PR not from my personal account, but from org, I cannot do the former (I am assuming anyone can always squash the commits themself when merging), so I did the latter.

@kubawerlos Thank you for looking into this!

The test suite currently reports this minor deprecation on PHP 8.5+, may I ask you to address this as well as part of this PR? 👍

PHP Deprecated: Non-canonical cast (integer) is deprecated, use the (int) cast instead in /home/runner/work/child-process/child-process/tests/AbstractProcessTest.php on line 538
