Subject: feat: Move code to blog

- Move most logic of the blog to blog.rs, making it easier to test.
- Now the file contains the creation date of the blog post to be parsed.
- Add chrono to parse datetime, so later we can order by date.
- Refactor gitlab pipeline, move `before_script` to a proper place.
