The docs says

manifests will be automatically generated and published as an asset attached to the GitHub release

but I can't seem to find them. I can however generate them myself with make manifests.

I want to deploy external-secrets in a dev env (without helm) using static manifests in a kustomize file similar to the following:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: external-secrets
resources:
  - https://github.com/external-secrets/external-secrets/releases/download/v0.6.1/external-secrets.yaml
