新增 IT 周刊页面

[TechQuery]

参考https://github.com/Open-Source-Bazaar/Open-Source-Bazaar.github.io/tree/main/pages%2Fpolicy 将 https://github.com/FreeCodeCamp-Chengdu/IT-Technology-weekly 所有 issue 的列表及详情页渲染出来，其核心接口逻辑为：

import { IssueModel } from 'mobx-github';

const list = await new IssueModel('FreeCodeCamp-Chengdu', 'IT-Technology-weekly').getAll({ state: 'all' });
