fix: make github-token optional for backward compatibility

- Changed github-token input from required to optional with default fallback
- Made GitHub App token generation conditional on secrets availability
- Updated all token references to fallback to github.token when not provided
- Ensures existing workflows without App credentials continue to work

This maintains compatibility with current users who don't pass github-token
explicitly or don't have GitHub App credentials configured.
