refactor: Switch from Packages API to Releases API for distribution

- Replace upload_to_packages scripts with create_release scripts
- Use Forgejo Releases API instead (standard for binaries)
- Windows: create_release.ps1 creates release and uploads exe + checksum
- macOS: create_release.sh creates release and uploads dmg + checksum
- Interactive credential prompts on first run
- UpdateManager queries releases/latest for updates
- Much simpler and matches standard open-source distribution
- Rename FORGEJO_PACKAGES_SETUP.md to reflect Releases approach
- Update documentation with Releases API examples
