Fix broken link in MenuTreeStorageInterface

Working on it.

Is the info still relevant? I'm not sure if it's documented anywhere else.

Hi @mortona2k,
This doc was foundational reading for understanding how Drupal (especially 6 & 7) stored menu items, taxonomy terms, etc., before full-fledged entity trees and interfaces were in place.
Conceptually it is relevant but not for inline documentation that most devs read.

Think some replacement may be needed vs just removing, but IS is incomplete.

Having a dead link is no use to anyone. I am fine with this removing that link only and having a followup to add documentation about menu ordering. One should search for an existing issue.

Fair enough, but for good practice think the issue summary should still be complete
