docs: // Clear wipes the diff for a particular key. It is called by ResourceDiff's
  // functionality to remove any possibility of conflicts, but can be called on
  // its own to just remove a specific key from the diff completely.
  //
  // Note that this does not wipe an override. This function is only allowed on
  // computed keys.
