Duo notifications don't show application details with LDAP provider

**Describe the bug**
When logging in via LDAP and using the DUO authenticator flow (part of the default authentication flow), the URL (or container address in my case) for Authentik is shown, rather than the requesting application. (I _believe_ the requesting application could be fetched from the BaseDN, but I’m not certain of this.)

**To Reproduce**
Steps to reproduce the behavior:
1. Setup an LDAP Application/Provider and attach the LDAP Provider to an Outpost.
1. Setup the DUO flow and configure it for a user.
1. Attempt to authenticate using LDAP and the DUO flow.

**Expected behavior**
The application name (or URL?) should be shown in the DUO prompt. (e.g., “Syncthing” when the incoming LDAP request matches the BaseDN of the Syncthing LDAP provider.)

**Screenshots**
N/A (can post if necessary though).

**Version and Deployment (please complete the following information):**
- authentik version: Discovered on 2023.1.1, but currently using 2023.2.0.
- Deployment: Docker via Ansible (closely mimics docker-compose depooyment)
