Subject: [PATCH] Update Gemfile dependencies and GitHub Actions workflow for
 improved compatibility

- Upgraded Jekyll from 3.10.0 to 4.3.0 and updated related plugins for enhanced functionality.
- Modified the Gemfile to specify versions for kramdown, kramdown-parser-gfm, and rouge.
- Updated the GitHub Actions workflow to use Ruby 3.1 and optimized the bundler installation process.
- Enhanced the Jekyll build command with version checks for better debugging and visibility.
