title: vault_jwt_auth_backend - Enable OIDC List method when unauthenticated using Terraform
body: <p>I have provisioned an OIDC auth method in a HashiCorp Vault instance, using Terraform.</p>
  <p>From the Vault UI, I am then able to enable a <code>List method when unauthenticated</code> flag, as depicted in the screenshot below, from the OIDC configuration method options.

  <p>The problem though is that currently, I'm only able to do so manually, which is definitely not the preferred approach. I'd like to be able to do this through my Terraform configuration, however this flag in question does not appear to be included in the <code>vault_jwt_auth_backend</code> argument reference list that is available from the official HashiCorp documentation found <a href="https://registry.terraform.io/providers/hashicorp/vault/latest/docs/resources/jwt_auth_backend#provider_config" rel="nofollow noreferrer">here</a>.</p>
  <p>Is there a way I can set this flag through my Terraform configuration?</p>
