Move Hugo Web-presence to GH-Pages

Hi there, a few months ago I decided, I would want to go to a form of webspace where I dont have to spend money. Although it’s only a few bucks, I thought it would be time to move on…​ this is basically a tutorial to move over to github pages…​ Edit from 20-04-2025: Previously I had a Makefile-based approach, but this was not the ideal way, so now I changed it to utilize github actions instead
