Provide updated samples

Provide working samples of Auth0 integration for Blazor Net9, working in conjunction with standard ASP Net Identity, in a hybrid environment. Update Samples when new versions come out.

All of the samples I can find for Blazor are for Net 6. Blazor changes FAST, so none of those are of any value.

Providing updated samples ensures that developers can more easily stay on top of technology changes and continue using your services.
