Update webhook documentation for lfd event

[mattyturner]

Add container.pickup_lfd_line.changed webhook event to documentation to provide customers with updates on the more accurate Shipping Line Last Free Day.

Terminal-provided Last Free Days (LFDs) have often been incorrect, leading to customer issues. This new webhook event allows users to be notified when the more reliable LFD, sourced directly from shipping lines, changes.

@matt fyi I am breaking down open-api.json into smaller YAML components so its easier to edit #145
