Add mariadb-container

The license is Apache 2.

It's been around for 6 years and it's actively maintained.

Downside: it doesn't include the most recent LTS version (11.4) or later versions.

Also please check the alphabetical order.

My only thinking is that perhaps we need a new section called "Images", as this project isn't a "tool", just an assortment of docker images.

[federico-razzoli]

I can make a new commit for that. Are there other items that I should move to the new section?

Thank you! This is the single other item:

[MySQL Docker](https://hub.docker.com/_/mysql/) - Official Docker images.

Maybe add container-registry.oracle.com/mysql/community-server:$tag for the official Oracle MySQL images.
