Update self-hosting docs

[wrycu]

The self-hosting docs refer to "Server Members Intent" in the settings page. I've clicked through all of the permissions I can find and am unable to locate that permission - I'm guessing it got renamed, as Discord loves doing. Any chance you can share what the new name is?

Hi @wrycu, you can't find it on that page because it isn't a permission, it's an intent :)
