InteractionContext.Guild always null

[erraineon]

The constructor is defined as...

public InteractionContext(IDiscordClient client, IDiscordInteraction interaction, IUser user, IMessageChannel channel = null)
{
    Client = client;
    Interaction = interaction;
    Channel = channel;
    Guild = (interaction as IGuildUser)?.Guild;
    User = user;
    Interaction = interaction;
}

No implementations of IDiscordInteraction also inherit IGuildUser, so Guild is always coalesced to null.

cc @Cenngo. This should be (interaction.User as IGuildUser)?.Guild;
