Domain related hotfix

Fixes the broken "Discover" page problem.

Migrating to use the github pages URL directly, in order to fix not just the current domain issue, but also make sure this type of thing never happens in the future even in the worst case scenario.

By hosting the website entirely on github pages, and using the github pages URL directly (instead of using a custom domain that requires maintenance) we can be sure that even in the worst case the app will keep running (unless github shuts down).
