由于本项目的依赖有点旧，让项目安装依赖的时候出现少量 deprecated

经排查，主要需要升级的 package 主要有这些：

1. react-intl，其底层依赖的 @formatjs/[email protected] [email protected] 改名了，所以原 package deprecated。
2. styled-component，它依赖了 @babel/plugin-proposal-class-properties，现在项目内的 styled-component 还是 6.x 的 beta 版，看起来需要升级。

虽然这些信息并没有影响，但是我有点洁癖看着有些不爽，我愿意 PR 来解决这些问题。
