terraform: Move away from bitnami charts and images

[lucas-koehler]

Is your feature request related to a problem? Please describe.

Bitnami made their images part of a paid subscription. Legacy images are still available under at dockerhub under bitnamilegacy but no longer updated. Thus, they don't receive security updates and newer versions won't be available.
Helm charts are still available but newer versions also will not be published anymore.

Describe the solution you'd like

Move away from Bitnami Helm charts and images.

Describe alternatives you've considered

• Move to paid Bitnami service: Not suitable for an Open Source project
• Stay on Bitnami legacy images and charts: Okay for now but not an option in the long run due to security risks
