Ability to hide JSON values by default

[loutPhilipps]

Is your feature request related to a problem? Please describe. When a secret can only be shown as a JSON and not as a key-value list (for instance if a value is not a string), all the values are shown at first when seeing the secret, while for the key-value view, values are hidden and can be revealed. This can lead to unexpectedly viewing secret values when expecting them to be hidden at first.

Describe the solution you'd like I'd like to be able to configure Vault so that those JSON secrets are hidden by default, and revealed the same way as for values in key-value view.

@loutPhilipps This should be solved now. I have the opposite issue, that I want the values to be visible by default. See issue: https://github.com/hashicorp/vault/issues/26732
