fix: modify Dumper.php file class name.

[HavenShen]

Operation composer du -o or composer install ..., src/Helpers/Dumper.php The class name and file name in it are inconsistent and do not conform to the psr-4 specification. Composer will prompt a notification, of course, it does not affect the entire function. It is recommended to fix it and keep the class name and file name consistent.

Deprecation Notice: Class SwooleTW\Http\Helpers\VarDumper located in ./vendor/swooletw/laravel-swoole/src/Helpers/Dumper.php does not comply with psr-4 autoloading standard. It will not autoload anymore in Composer v2.0. in phar:///usr/local/Cellar/composer/1.10.6/bin/composer/src/Composer/Autoload/ClassMapGenerator.php:201
