Subject: [PATCH] Remove the unspecced `room_id` field in the `/hierarchy`
 response. (#13365)

The `room_id` field represented the parent space for each room
and was made redundant by changes in the API shape where the
`children_state` is now nested underneath each `room`.

The room ID of each child is in the `state_key` field and is still
available.
