Used mariadb image is 2 years old https://github.com/bianjp/docker-mariadb-alpine . https://hub.docker.com/r/bianjp/mariadb-alpine. We should switch to official mariadb image

@fleischsalatinspace I tried updating to the official mariadb:latest today and ran into a few problems:

1. Maria was unable to load the db from the volume due to some combatability issues between versions. We could try to solve this, but it seems like dumping and restoring the db would be safer
2. The official image based on ubunut:focal does not have zip installed, so our normal setup process of unzipping the sql dump with exec won't work without first installing zip somehow.

Otherwise, it seems to be working just fine, php mysql adapter has no problems using latest official image.
