Deduplicate code for OpenAPI Media Type Objects

These are common to requests and responses and can be found in the
`content` field.

This also adds more locations to where we can find examples and makes
sure that the order of where we look for them is consistent.

{{/*
Render a map of [Media Type Objects](https://spec.openapis.org/oas/v3.1.1#media-type-object).
This map can be found as the `content` field of requests and responses.
Parameters:
* `content`: A map of MIME type to Media Type Object
* `kind`: the kind of object that is rendered, either `request` or `response`.
* `anchor_base`: a prefix to add to the HTML anchors generated for each object
This template renders:
* Object tables if the map contains an `application/json` MIME type, or a
table with the MIME types and the corresponding description of the object.
* The examples of the Media Type Objects.
