feat: Direct guide to Register New User Keycloak Form via loginAuthorizationCodeFlow breaks

[s681562]

Description

I follow the example ...

Uri authorizationEndpointUri = Uri.parse("https://.../realms/.../login-actions/registration");
await manager!.loginAuthorizationCodeFlow(
    discoveryDocumentOverride: manager!.discoveryDocument.copyWith(
      authorizationEndpoint: authorizationEndpointUri,
    )
);

But it doesn't work like expected. Some params are missing.
The direct register user keycloak html form popup is not showing.

Which additional params in loginAuthorizationCodeFlow must be set?

Clearly describe what you are looking to add. The more context the better.

As we discussed here: #54 (reply in thread)
it's a problem with keycloak configs, not the oidc package
