fix(tests): update DiscordNewSessionHandlerTests for deferred response pattern

The Command_ShouldRenderEmbedOnSuccess test asserted the presence of
WithEmbeds in DiscordNewSessionCommand.cs. After switching to deferred
responses (InteractionCallback.DeferredMessage + ModifyResponseAsync),
embeds are now set via message.Embeds = embeds instead.
