MongoDBPurger doesn't purge chunks collection

Bug Report

Q	A
Version	2.2.0

Summary

I have GridFS document with #[File] attribute. It stores data in two collections xxx.files and xxx.chunks. MongoDBPurger drops only xxx.files but keeps xxx.chunks.

Current behavior

MongoDBPurger drops only xxx.files collection for GridFS documents.

Expected behavior

MongoDBPurger drops both xxx.files and xxx.chunks collections for GridFS documents.

How to reproduce

Add a document:

use Doctrine\ODM\MongoDB\Mapping\Annotations\File;
use Doctrine\ODM\MongoDB\Mapping\Annotations\Id;

#[File(bucketName: 'report')]
class Report
{
    #[Id]
    private string $id;

    #[File\Filename]
    private string $name;

    public function getId(): string
    {
        return $this->id;
    }

    public function getName(): string
    {
        return $this->name;
    }
}

Create the schema:

bin/console doctrine:mongodb:schema:create

After that you will see 2 collections in your db: report.files and report.chunks.

Run MongoDBPurger:

#[AsCommand('debug')]
class DebugCommand extends Command
{
    public function __construct(private MongoDBPurger $purger)
    {
        parent::__construct();
    }

    protected function execute(InputInterface $input, OutputInterface $output): int
    {
        $this->purger->purge();

        return Command::SUCCESS;
    }
}

As MongoDBPurger calls $schemaManager->createCollections() you will get an error:

/var/www $ bin/console debug

In CreateCollection.php line 257:
                                                   
  Collection mydb.report.chunks already exists.
