Fix prism-react-renderer imports with fallback handling

- Move prism theme imports directly into docusaurus.config.js
- Add try-catch for robust error handling
- Remove dependency on separate theme files to avoid import issues
- Ensure compatibility across different environments and Node.js versions

This resolves the 'Cannot find module prism-react-renderer/themes/github/index.cjs.js' error
that was occurring in CI builds.
