Updating to OpenTalk Controller v0.30.0

Change to the OpenID Connect integration

The OpenID Connect integration has been changed to support more authentication flows for clients. Previously, ID tokens were used to synchronize user information from the OpenID Provider with the OpenTalk database. Now, the userinfo endpoint is used to fetch user information directly from the OpenID Provider, removing the need for the ID token.

OpenID Providers (e.g. Keycloak) must be updated to include the documented fields in the userinfo endpoint instead of the ID token.
