Examples of by-component link relations in SSPs

[aj-stein-nist]

User Story

As an OSCAL tool developer, to best understand how to cross-reference components through specific link types, I would like to see examples of it to understand how to consume and generate SSPs with the correct OSCAL JSON, XML, and YAML structure.

Goals

Add examples to clearly demonstrate to downstream developers how they should consume or generate these relationships with their tooling, per feedback #1022 (comment) after the completion of #1452.

Dependencies

Definitely looks worthwhile, I would like @david-waltermire-nist to weight in if this belongs in Sprint 60, 61, or left in backlog for now.

Marking this as blocked until #1910 is completed, and then it will be ready for "Needs Refinement" and determination if we edit this issue or replace it with a different one.
