Use the Default Format set by the ErrorLogHandler (#19160)

Currently, the defaultFormatter, set in Writer.php adds a `\n` at the end of each log, while the ErrorLogHandler removes that `\n` in its own `getDefaultFormatter()`

ErrorLogHandler.php:60
```php
    /**
     * {@inheritDoc}
     */
    public function getDefaultFormatter()
    {
        return new LineFormatter('[%datetime%] %channel%.%level_name%: %message% %context% %extra%');
    }
```
