Begin publishing flattened, ready-to-deploy yaml templates of the controller

[amisevsk]

Description

Currently, the DevWorkspace operator is only deployable by setting environment variables and running kustomize. To support deploying the operator via chectl, we need to publish processed yamls that can be referenced in chectl without the need to run kustomization. This could potentially be done via GitHub releases to avoid filling the repo with thousands of lines of yaml.
