Easy Github Pages

[omarcostahamido]

Describe the bug
Following discussion #144 might not be enough to have github pages running smoothly.

• If the repo has other branches with deployed actions it will not suggest the jekyll template. So I suggest adding it to the repo ourselves already.
• once successfully deployed, some pages won't load, like the recent blog entries on the main page, also the image and sound assets won't load. this is due to missing base.url on these pages.
• additionally I noticed that the _config.yml instructions for github pages are missleading. The baseurl here does nothing on this github pages deployment - it is the one from the workflow file.

I am proposing a pull request in the next couple of minutes to address all these.

• this issue refers to clarify github pages support in config.yml #58
