Describe the problem caused by this bug

I am triggering an OAuth flow like described here: https://zitadel.com/docs/guides/integrate/login-ui/oidc-standard.

Like described in the documentation, the Zitadel API returns me an authRequestId like V2_224908753244265546 (prefixed with "V2_"). But the login app of the latest version (commit sha of main: d5695a0) only handles authRequestIds prefixed with saml_ or oidc_. See:

typescript/apps/login/src/app/login/route.ts

Line 110 in d5695a0

if (requestId.startsWith("oidc_")) {

To reproduce

Steps to reproduce:

1. Get an authRequestId like:

https://login.example.com/oauth/v2/authorize?client_id=170086824411201793%40yourapp&redirect_uri=https%3A%2F%2Fyourapp.example.com%2Fauth%2Fcallback&response_type=code&scope=openid%20email%20profile&code_challenge=9az09PjcfuENS7oDK7jUd2xAWRb-B3N7Sr3kDoWECOY&code_challenge_method=S256&login_hint=minnie-mouse

2. Use the authRequestId to login the user like:

https://login.example.com/loginname?organization=<organizationId>&client=<clientId>&requestId=<authRequestId>&state=<state>
