Get an images upload request. Will return a pre-signed S3 URL to which all the images will be uploaded (zipped). Generated URL has a 5 minute expiration time. Upload request id should match the one specified in https://docs.things5.com/reference/create-new-document

Use generated URL to upload the ZIP file containing the images: use a tool like curl or an HTTP client to send a PUT request to the presigned URL, including the ZIP file in the body of the request (as form-data).
