Block 3, Task 4: Combine GitHub Pages With GitHub Actions

[mbannert]

Work to create an automated markdown report. (combine the previous two tasks).
The workflow could look like this.

1. download OECD data
2. transform it into a data format to create a cool time series graph (tstools, tsbox, dygraphs (for interactivity) are packages to do so)
3. create an .Rmd template file and knit it to HTML and add the graph to it.
4. make sure the output is rendered to the docs folder.
5. activate github pages in the root/docs flavor
