[supervisor] Add warning about race condition
ERL-724: "During a 'gentle' shutdown, supervisors unlink from their children before sending shutdown signals to them. This can lead to a race condition in supervision trees, when the timeout for gentle shutdown of a parent supervisor expires and it kills a child supervisor that has just unlinked from a child of its own, leaving the child supervisor's own child still running after its supervisor is killed." This commit adds a warning about this in the documentation.
