florianJacques has created Issue #2851: Transaction level not working when use closure in laravel-mongodb. This Jira ticket was filed by GromNaN

Issue Text:
The transaction level remains at 0 when we use laravel automatic transactions.

```php
$connection->transaction(function () use ($connection)

{ dump($connection->transactionLevel()); }

);
```
Display 0.

Here's a suggested fix

```php
/**

• Static transaction function realize the with_transaction functionality provided by MongoDB.
  *
• @param int $attempts
  */
  public function transaction(Closure $callback, $attempts = 1, array $options = []): mixed
  {
  $attemptsLeft = $attempts;
  $callbackResult = null;
  $throwable = null;

$callbackFunction = function (Session $session) use ($callback, &$attemptsLeft, &$callbackResult, &$throwable) {
$attemptsLeft--;

$this->transactions = 1;

if ($attemptsLeft < 0)

{ $session->abortTransaction(); $this->transactions = 0; return; }

// Catch, store, and re-throw any exception thrown during execution
// of the callable. The last exception is re-thrown if the transaction
// was aborted because the number of callback attempts has been exceeded.
try

{ $callbackResult = $callback($this); }

catch (Throwable $throwable)

{ throw $throwable; }

finally

{ $this->transactions = 0; }

};

with_transaction($this->getSessionOrCreate(), $callbackFunction, $options);

if ($attemptsLeft < 0 && $throwable)

{ throw $throwable; }

return $callbackResult;
}
```
