Description
Describe the bug
DoOIDCCallbackAsync can't be called with an unauthenticated client, similar to #348
VaultSharp Version
1.17.5.1
Vault Version
1.18.4
Does this work with Vault CLI?
Yes
Sample Code Snippet
var tempAuthMethod = new NullAuthMethodInfo();
var tempClient = new VaultClient(new VaultClientSettings(vaultUri.ToString(), tempAuthMethod));
var callbackUrl = (await tempClient.V1.Auth.JWT.GetOIDCAuthURLAsync($"{CallbackHost}/oidc/callback", roleName: "oidc-role", mountPoint: "oidc").ConfigureAwait(false)).Data.AuthorizationURL;
// Getting callback data is omitted for brevity
string state = "";
string code = "";
// Exception!
var token = (await tempClient.V1.Auth.JWT.DoOIDCCallbackAsync(state, HttpUtility.ParseQueryString(callbackUri.Query)["nonce"], code, mountPoint: "oidc").ConfigureAwait(false)).AuthInfo.ClientToken;public class NullAuthMethodInfo : CustomAuthMethodInfo
{
public NullAuthMethodInfo() : base("null", () => null)
{
}

Any additional info
Adding unauthenticated: true should be enough to fix this issue.
