How to sync RELATED_IMAGE environment variables with spec.relatedImages when using image digests? #6923

Question
What did you do?
Hi, we have several operands which we define in our manager's kustomization file like so: https://github.com/odigos-io/odigos/blob/5b5b1c02b1184936ab223265a6087071be258da3/operator/config/manager/kustomization.yaml#L6-L11
These get updated to the latest version when we update the Makefile's VERSION variable
The manager consumes these values through RELATED_IMAGE env vars we manually defined in the manager's manifest: https://github.com/odigos-io/odigos/blob/5b5b1c02b1184936ab223265a6087071be258da3/operator/config/manager/manager.yaml#L80-L83
When the bundle is generated with USE_IMAGE_DIGESTS, the output CSV correctly updates the image SHA to the latest version under spec.relatedImages, but the environment variables in the output CSV don't get the latest SHA (unless we update those values in the manifest)
Is there a recommended best practice to keep the environment variables in sync with the digest SHA? Should we not be defining those manually? Just looking for any recommendations, thank you
What did you expect to see?
Setting USE_IMAGE_DIGESTS updates spec.relatedImages and the matching RELATED_IMAGE environment variables
What did you see instead? Under which circumstances?
RELATED_IMAGE environment variables use the digest SHA for the version specified in the manager's manifest, unless the version is updated in those variables too
