PicnicTable - Create a sample with Authentication

[Nordes]

OpenId? or basic Dotnet authorization?

Probably do an example using Azure AD with Graph API. I think it's more common nowadays for any organization.

I have worked recently on a better example using Graph API (Azure Active Directory). It works, but I still have too many workaround to make it clean.

Maybe soon I'll add a 3rd project with authentication.
