Mention MariaDB on front page of deployer.org

[ottok]

Hi!

Based on https://github.com/search?q=repo%3Adeployphp%2Fdeployer%20mariadb&type=code it seems Deployer supports MariaDB. Can you please update the front page of https://deployer.org/ to mention MariaDB?

Thanks!

I filed this as an issue of type "feature request", and not intentionally as a discussion.
