Website does not have the correct trademark disclaimer

[thisisobate]

As part of our ongoing effort to cncf/techdocs#198, we noticed that the website does not pass the trademark criteria on CLOMonitor.

To fix this:
Head to the source code of the website. In the <footer> section, add a disclaimer or link to the Linux foundation trademark disclaimer page:

         please see our <a href="https://www.linuxfoundation.org/legal/trademark-usage">Trademark Usage page</a>.
   </p>

      </ul>
 </footer>

Thanks, we'll check it.
