Update security.rst

Add third argument on example of config of DefaultLoginRateLimiter.

After migrate 6.2 to 6.4.1 i got an error :
Too few arguments to function Symfony\Component\Security\Http\RateLimiter\DefaultLoginRateLimiter::__construct(), 2 passed in /var/www/html/var/cache/dev/ContainerJcwPZ89/getSecurity_Listener_LoginThrottling_MainService.php on line 41 and exactly 3 expected

in the class

```php
/**
 * `@param` non-empty-string $secret A secret to use for hashing the IP address and username
 */
public function __construct(RateLimiterFactory $globalFactory, RateLimiterFactory $localFactory, #[\SensitiveParameter] string $secret)
{
    if (!$secret) {
        throw new InvalidArgumentException('A non-empty secret is required.');
    }

    $this->globalFactory = $globalFactory;
    $this->localFactory = $localFactory;
    $this->secret = $secret;
}
```

So,  it will be nice to update these config example section !
