Upgrade mariadb Helm chart to 8.0.0 (#48)

Upgrade mariadb Helm chart to 8.0.0

The names of the values changed in the new Helm chart, see [1]. Thus the
Helm chart ships breaking changes and therefore bump the major version
of this Chart.yaml (not sure if you use semver?)

Furthermore, there is a bug [2] where not setting the root password
results in the mariadb entering a CrashLoopBackOff when re-installing
it. Thus set it (as done in the mysql values already).
