Update Oracle image for docker-compose.

[KevinEdwardBerry]

Description

The current listing for an Oracle image in the docker-compose file, namely sath89/oracle-12c, no longer exists. I updated the file to use an existing copy of the current image (first thing that came up in a search on hub.docker.com ). Feel free to change it. I just wanted to make sure others who attempt to use the docker-compose file would not run into the same issue.

Good catch. I updated to the official oracle version. It requires logging into docker hub and agreeing to terms of service, but it's official.
