feat(query): before pagination

[TorstenDittmann]

Adds the ability to paginate before an id.

Technically, it will be done the way after is paginated - just that the ordering is reversed and after we fetched the results we invert the array. Sadly there is no easy implementation, since negative offsets are not a thing.

Breaking changes:

• renames orderAfter to cursor
• adds cursorDirection with after by default

Super small change, otherwise looks good 👍🏻
