fix: replace deprecated fs.rmdir with recursive removal logic

[nexckycort]

Summary

This pull request addresses a deprecation warning in Node.js regarding the use of fs.rmdir(path, { recursive: true }). In future versions, this method will be removed.

To resolve this, I replaced fs.rmdir with fs.rm(path, { recursive: true }) as recommended by the warning. This change maintains the functionality while adhering to future Node.js standards.
