Change jekyll highlighter to rouge

Got this mail from GitHub:

You are attempting to use the 'pygments' highlighter, which is currently
unsupported on GitHub Pages. Your site will use 'rouge' for highlighting
instead. To suppress this warning, change the 'highlighter' value to
'rouge' in your '_config.yml'. For more information, see
https://help.github.com/articles/page-build-failed-config-file-error/#fixing-highlighting-errors.
