[Bug]: Pest 4: Unknown option "--processes" when Using Sharding

What Happened

./vendor/bin/pest --processes=12 --shard=1/4 --parallel
   Symfony\Component\Process\Exception\ProcessFailedException

  The command "'php' './vendor/bin/pest' '--processes=12' '--cache-directory' '/Users/adam/Projects/app/vendor/pestphp/pest/.temp' '--no-output' '--list-tests'" failed.

Exit Code: 2(Misuse of shell builtins)

Working directory: /Users/adam/Projects/app

Output:
================

   INFO  Unknown option "--processes".



Error Output:

/vendor/bin/pest --processes=12 --parallel
works normally

How to Reproduce

run /vendor/bin/pest --processes=12 --shard=1/4 --parallel

Sample Repository

Notes

This is happening on my local and CI.

Our CI runs faster when we have 12 be the process but sucks that shards seem to break process

Reproduce the issue with ./vendor/bin/pest --processes=12 --shard=1/4 --parallel, then compare it with the working --processes=12 --parallel command. Start at the Pest CLI handling for sharding and process options, using the failure location in vendor/symfony/process/Process.php:269 as context. Done means sharded parallel runs accept --processes and the behavior is covered by an appropriate test.
