[Bug]: PHPStan namespace is not discoverable by plugin-arch

[aymanrady]

What Happened

arch('arch')
    ->expect('App')
    ->toOnlyUse('PHPStan');

 FAILED  Tests\ArchTest > arch                                                                                                                                     
  Expecting 'App' to only use 'PHPStan'. However, it also uses 'PHPStan\Analyser\Scope'.

How to Reproduce

cat > composer.json <<EOF
{
  "autoload": {
    "psr-4": {
      "App\\\\": "src/"
    }
  }
}
EOF
composer require --dev pestphp/pest phpstan/phpstan
vendor/bin/pest --init
mkdir src
cat > src/SomeClass.php <<EOF
<?php
namespace App;

use PHPStan\Analyser\Scope;

class SomeClass {}
EOF
cat > tests/ArchTest.php <<EOF
<?php
arch('arch')
    ->expect('App')
    ->toOnlyUse('PHPStan');
EOF
vendor/bin/pest tests/ArchTest.php

Notes

PHPStan doesn't register its namespace with composer relying on a bootstrap file with a custom autoloader.
