Reading a secret from vault

[Rand0mF]

What happened?

I want to read a secret from vault, only watching it, not taking control of it.
Not 100% sure if this provider is meant to do that, as it's lacking documentation. Though I think it should be, as the terraform module it is based on can do that.
From the API it looks like it could be possible but every Secret object requires dataJsonSecretRef (for writing the secret).

Though the API documentation does not label this field as mandatory, in fact it is as following error occurs when applying without it:

The Secret "test" is invalid: spec: Invalid value: "object": dataJsonSecretRef is a required parameter

How to reproduce:

apiVersion: generic.vault.upbound.io/v1alpha1
kind: Secret
metadata:
  name: test
spec:
  forProvider:
    path: "kv/some/path"
  providerConfigRef:
    name: vault-provider-config

What environment did it happen in?

Version 0.3.0 of the provider.
