Expose Category and Group IDs to admins

[JammyDodger]

我建议为数据浏览器添加更多类似 user_id 的参数，例如这个 Feature request for groups：

Param dropdown for group_id in data explorer query

I’d love to be able to specify something like this: -- [params] -- groups.id :group_id to get a parameter input that’s a dropdown of groups. I’ve named the value group_id here because I assume that’s what such a dropdown would give me.
