[#2270] Change docker image to container-registry.oracle.com/mysql/community-server:9.3.0

from `docker.io/mysql:9.2.0`
to `container-registry.oracle.com/mysql/community-server:9.3.0`

I found the registry in the official MySQL documentation:
https://dev.mysql.com/doc/refman/9.3/en/docker-mysql-getting-started.html#docker-download-image

The one from docker.io doesn't seem to work with testcontainers.
