Kubernetes manifest file not updated for v1.9.0

[dmitchsplunk]

Bug Report

Which version of the demo you are using?

v1.9.0

Symptom

The Kubernetes manifest file hasn't been updated for v1.9.0, it still refers to the v1.8.0 images. Also, v1.9.0 specific enhancements appear to be missing, such as the migration from postgres to flagd for feature flags.

What is the expected behavior?

The manifest file is updated with each release.

What is the actual behavior?

The manifest file was not updated for release 1.9.0.

Reproduce

Deploy the application using

kubectl apply --namespace otel-demo -f https://raw.githubusercontent.com/open-telemetry/opentelemetry-demo/main/kubernetes/opentelemetry-demo.yaml

v1.8.0 of the application is deployed instead of v1.9.0.

Additional Context

I understand that the manifest file is provided for convenience, and that I can generate my own using the Helm chart. But I would like to understand if the manifest file will be updated with each release going forward, as it is indeed convenient. Thank you!
