Reject Grant Request

Indicate that you will not process this grant. Calling this endpoint moves the Grant Request's status to `rejected` and emits a `grant_request.updated` webhook event. The Donor Account itself is unaffected; future Grant Requests from the same donor can still be processed. <Warning> A Grant Request that is already `submitted` or `rejected` cannot be updated. Subsequent calls return status `409 Conflict`. </Warning>
