Fix CI: Use ACCESS_TOKEN instead of FORGEJO_TOKEN to match existing secret

- Changed workflow to use ACCESS_TOKEN (your existing secret name)
- Removed extra spaces that were causing 'Bad substitution' errors
- Should now properly detect and use your ACCESS_TOKEN secret
- Fixes the upload step that was failing in Build 76
