Feature request: Optional trigger for "Space XXXX ended" Webhook-Posts

[Kazandu]

It would be cool to have the bot edit its Space live posts to "Space ended", maybe with a custom field "End Text" where people could add an info about how to optain the finished space (Like: "Head over to some.website/spaces to get the archive")
