Update credit note

PATCH https://api.light.inc/v1/credit-notes/{creditNoteId}

Updates a credit note in draft status. Fields sent as null clear the value; omitted fields remain unchanged.

Only in DRAFT (CREDIT_NOTE_CANNOT_BE_MODIFIED). The null rule in the description holds for description, currency, amount, documentNumber and the FX overrides only; companyEntityId, businessPartnerId, documentDate, areLinesWithTax and customProperties cannot be clearednull leaves them unchanged. Changing businessPartnerId silently clears companyEntityId when the entity isn't one the new vendor is enabled for. documentDate also rewrites the posting date.
