[GH-ISSUE] - [ #173] Order Product API does not return `order_product…

…_id` (#193)

<!-- Ticket number or summary of work -->
# [DEVDOCS-5847]


## What changed?
<!-- Provide a bulleted list in the present tense -->
* Add note indicating that the response `id` is required when creating
order shipments

## Release notes draft
<!-- Provide an entry for the release notes using simple, conversational
language. Don't be too technical. Explain how the change will benefit
the merchant and link to the feature.

Examples:
* The newly-released [X feature] is now available to use. Now, you’ll be
able to [perform Y action].
* We're happy to announce [X feature], which can help you [perform Y
action].
* [X feature] helps you to create [Y response] using the [Z query
parameter]. Now, you can deliver [ex, localized shopping experiences for
your customers].
* Fixed a bug in the [X endpoint]. Now the [Y field] will appear when
you click [Z option]. -->
* Added a note to /v2/orders/{order_id}/shipments letting merchants know
that the 'id' response is needed when creating order shipments.

## Anything else?
<!-- Add related PRs, salient notes, additional ticket numbers, etc. -->
