UPBGE: Create weekly automatic builds

Currently it is limited to linux and Windows builds as MacOS builds spend build time (80 min) multiply per 10 (around 800min) and we have around 2000-3000min/month for actions.
Linux spends 1:1 (80 minutes build spends 80 minutes available) and Windows spends 1:2 (80 minutes build spends 160 minutes available).
I will see if I can create a mirror-fork to make macOS build in a monthly way.
