Fix Forgejo upload API endpoint to match working composefs CI

- Use correct API endpoint: /api/packages/particle-os/debian/pool/trixie/main/upload
- Match the format used in the working composefs CI
- This should resolve the 404 page not found errors
- Build is working perfectly, just need correct upload URL
