fix: Update release badge to include pre-releases

- Add include_prereleases parameter to GitHub release badge
- Fixes badge showing 'no releases' when only pre-releases exist
- Badge will now display v1.0.0-rc and other pre-release versions

This ensures the release badge shows version information for
release candidates and other pre-release versions.
