Fix GitHub Pages: Add .nojekyll and disable Jekyll in docs directory

- Add .nojekyll file to docs/ directory to disable Jekyll processing
- Add _config.yml with explicit Jekyll disable configuration
- This should resolve the 'No such file or directory' error in GitHub Pages
- GitHub Pages should now serve Sphinx-generated static HTML files directly
- Documentation should be accessible at https://vcon-dev.github.io/vcon-lib/
