fix: Fix the images used by the Orchestrator DB creation Job

[rm3l]

Description of the change

We should not use container images from Docker Hub. We should also be consistent and use images that have their counterpart available on registry.redhat.io when publishing the Helm Chart.
This PR makes sure to reuse the existing DB image in the Orchestrator DB creation Job. This way, there won't be any impact on our publishing process or our airgap docs.

Existing or Associated Issue(s)

Fixes https://issues.redhat.com/browse/RHIDP-7457

Additional Information

The procedure to install the Orchestrator-flavored RHDH on OpenShift should continue to work.

Checklist

• Chart version bumped in Chart.yaml according to semver.
• Variables are documented in the values.yaml and added to the README.md. The pre-commit utility can be used to generate the necessary content. Use pre-commit run -a to apply changes.
• JSON Schema template updated and re-generated the raw schema via pre-commit hook.
• List tests pass for Chart using the Chart Testing tool and the ct lint command.
