Update a holiday calendar. Fields not passed are not updated.

## Path parameters

## Request body

- PresenterUpdateHolidayCalendarRequest
  - `type` 'authentication' | 'challenge-request' — Evaluation intention
  - `parent_id` integer — Calendar parent ID. Holiday calendars can have parent-child relationships, creating a hierarchy. Child calendars inherit holidays from their parent calendars.

  - `external_id` string — Customer-provided external ID field for customer monitoring and tracking.
  - `metadata` string — Any data object with key/value pairs. No limit on length. **Note**: This field must not be used to send Personally Identifiable Information (PII), Payment Card Industry (PCI) data, or any sensitive/regulated information. Metadata fields are intended for operational, non-sensitive data only. For sensitive data, use the specific parameters designed for that purpose.
