Issue running AsyncFacade run function

[andreinocenti]

Hi,

I'm using your package version 4.0.0 with Laravel 10. I followed the instructions for installation of the package and I have both PCNTL and POSIX extensions installed.

I runned the eg. code below

for ($i = 1; $i < 20; $i++) {
            AsyncFacade::run(function () use ($i) {
                sleep(1);

                return $i;
            });
        }

And I got this error:

Declaration of VXM\Async\Runtime\ParentRuntime::createProcess($task, ?int $outputLength = null, ?string $binary = 'php'): Spatie\Async\Process\Runnable must be compatible with Spatie\Async\Runtime\ParentRuntime::createProcess($task, ?int $outputLength = null, ?string $binary = 'php', ?int $max_input_size = 100000): Spatie\Async\Process\Runnable
