fix: Added overload of AddKeycloakWebAppAuthentication

[awchristie1]

Added overload of AddKeycloakWebAppAuthentication due to dotnet 8.0 causing breaking changes. The sub claim is not mapped into the user's claims list without disabling claimMapping. Exposing the ConfigureOpenIdConnectionOptions allows this to be worked around.

Maybe we should include this workaround into core of this library instead of adding workaround?

However, this was what i used to get the original claims from keycloak with the new overload:

builder.Services
    .AddKeycloakWebAppAuthentication(builder.Configuration, 
        configureOpenIdConnectOptions: options => { 
            options.MapInboundClaims = false;  
            options.SaveTokens = true;  // for logout
        }) ;

Please do not delete build.yml

@awchristie1 could you please rebase to main and not remove build.yml?
