Move Atahualpa to Github

I just also asked in a PM to juggledad and Flynn if it would be okay with them to continue keeping atahualpa updated on github.
It would be much more suited than this forum to publish fixes/updates to keep it running. Right now Atahualpa can still be used even with PHP 8.2 - but if this forum shuts down it would be nice to have a place where the remaining users could discuss things.

Linking to Github then could also be done here:
https://wordpress.org/support/theme/atahualpa/

So should bytesforall.com website shut down completely it's a better remaining place vs the wordpress.org forums.
