Feature: Need to add a new domain name

[Chever-John]

🚀 Feature Proposal

I recently discovered that the official domain name of leetcode has changed from leetcode-cn.com to leetcode.cn. This means that the plugin needs to be transformed, and I'm willing to help if I can~

behavior: #798 #799

Motivation

If you don't change it, the Chinese leetcode will not be available anymore.

Contribution

I will add a new domain name in this file

是域名的问题，我基于官方插件修改的版本修复了这个问题，详情看这里：labuladong 的 vscode 刷题插件

@labuladong Yes, it is indeed a problem with the domain name. Thank you for contributing such a good plugin, I'll try it out. Also hope the official can modify the project soon.

This link solves the problem; just replace the domain name.
Of course, I would still like to submit a PR to solve this problem and ask the official to take care of this issue. I am willing to contribute to it.
