Incorrect `InvalidLiteralArgument` when usage `dirname()`

```php
function test(): bool {
    $path = dirname(__DIR__, 4);
    return strlen($path) > 6 && str_contains($path, 'vendor');
}
```

For no duplicate `dirname(__DIR__, 4)` I use variable `$path`, but psalm throw `InvalidLiteralArgument`. Seems, it's incorrect.
