Issue Summary
The /v2/RegulatoryCompliance/SupportingDocuments does not include the File body parameter in the endpoint details.
It's also not referenced directly in the API description in the website: https://www.twilio.com/docs/phone-numbers/regulatory/api/supporting-documents#create-a-supporting-document
The only mention I can find of it is in this example which also requires using multipart/form-data. The documentation and openapi spec only mentions application/x-www-form-urlencoded.
This is the section where the attribute is missing: https://github.com/twilio/twilio-oai/blob/main/spec/yaml/twilio_numbers_v2.yaml#L5432-L5674
