Replace for the secretKeyRef doesn't work

[DmytroRybka]

Hi,

When I look into the code I see that it should be possible to use the "placeholder" for SecretKeyRef but when I use it I'm getting the validation error
is invalid: spec.template.spec.containers[0].env[6].valueFrom.secretKeyRef.key: Invalid value: a valid config key must consist of alphanumeric characters, '-', '_' or '.' (e.g. 'key.name', or 'KEY_NAME', or 'key-name', regex used for validation is '[-. _a-zA-Z0-9]+')

• name: kafka_api_key
  valueFrom:
  secretKeyRef:
  name: myservice
  key: gcp:secretmanager:projects/111222666333/secrets/kafkaKey

The secretKeyRef should point to K8s secret and then the value of this secret can be substituted by the secrets-init webhook
