/**
 * Sets the 'api_json' format for requests to JSON:API resources.
 *
 * Because this module places all JSON:API resources at paths prefixed with
 * /jsonapi, and therefore not shared with other formats,
 * \Drupal\Core\Routing\RequestFormatRouteFilter does correctly set the request
 * format for those requests. However, it does so after other filters, such as
 * \Drupal\Core\Routing\ContentTypeHeaderMatcher, run. If those other filters
 * throw exceptions, we'd like the error response to be in JSON:API format as
 * well, so we set that format here, in a higher priority (earlier running)
 * filter. This works so long as the resource format can be determined before
 * running any other filters, which is the case for JSON:API resources per
 * above.
