Expand type aliases

I thought that would be implemented (at least for depth = 1, see #557), but I cannot see on hover what the record contents of that type are:

I think the hover help should say:

type dispatchable = Api.dispatchable = {id: string, version: int, name: string}

happens with ReScript 10.1.4 and the latest published 11 as well.

Created a PR with a test to show what I mean: #834
