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.

• [x] 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 .... #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 ...
