/**
 * Override of Schema.example and Schema.examples field inside the Header Objects.
 *
 * Header Object has two fixed fields:
 *  - `example` of type `Any`
 *  - `examples` of type `Map[string, Example Object | Reference Object]`
 *
 * OpenAPI 3.1 specification excerpt that defines the override behavior:
 *
 * The example value SHALL override the example provided by the schema.
 * Furthermore, if referencing a schema that contains an example, the examples value SHALL override the example provided by the schema.
 *
 * NOTE: this plugin is idempotent
