Automatically update and publish to GitHub pages using GitHub actions (…

…#18)

Hello, I have upgraded uglify-es to uglify-js, and added the feature of
using GitHub actions to automatically update and publish to GitHub
pages.

Here are the specific changes:
- Add GitHub actions to publish on GitHub pages;
- Change uglify-es to uglify-js;
- When building, download uglify-js from GitHub releases instead of git;
- When publishing, use CDN(`registry.npmmirror.com`) instead of local
files for uglify-js;

Update steps:
1. On the GitHub actions page, manually run workflow `update` to build
and publish to the gh-pages branch;
2. Let GitHub pages use gh-pages branch;
