Use github action to generate weekly

[at15]

A follow up on #175, we need to generate both md files and html if we want to use github pages.
We have dy-bot to run weekly generator and relies on netlify for running jekll, both can be implemented using github action.

• Dockerfile that contains latest weekly generator and jekyll
• create and close issue weekly
• On issue close, trigger generator, push to master branch
• Update docs folder for jekyll ... or do we really need it? btw: the theme looks really bad .... Better gh-pages style #1

btw: @gaocegege why we need to check in the generated html from jekyll? I think both gh-pages and netlify allows you to build from md directly?

The issue logic is working, but I haven't write the commit and push logic ...
