Hardcode a value a data field, usefull for simple templates that can be patched by Flux

[Richard87]

Is your feature request related to a problem? Please describe. I want to override part of a secret with values from Flux substitutes, imagine this secret:

apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
  name: database
  namespace: default
spec:
  refreshInterval: 1h
  secretStoreRef:
    kind: ClusterSecretStore
    name: azure-store

  data:
    - secretKey: password
      remoteRef:
        key:db_password
    - secretKey: username
      remoteRef:
        key: db_username
    - secretKey: password
      remoteRef:
        key: db_password

    - secretKey: dbname
      value: "will be patched by flux"
    - secretKey: dbhost
      value: "will be patched by flux"
   

Describe the solution you'd like I want to specify a secret value in the data section

Describe alternatives you've considered Create a template (hard to target by kustomize patch), add (in this example) dbname/dbhost to key vault
