Expose Category and Group IDs to admins

[JammyDodger]

データエクスプローラーの投票は、次のような user_id スタイルのパラメーターを増やすことです。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.
