openapi: POST /v2/generate-upload-url

The `presignedUrl` and `formData` fields can be then used to upload the file to the S3 bucket, directly from the browser if necessary. Here is an example:

```js
// data contains the presignedUrl and formData fields from the response

const formData = new FormData()
Object.entries(data.formData).forEach(([key, value]) => {
  formData.append(key, value)
})
formData.append('file', file)
const upload = await fetch(data.presignedUrl, {
  method: 'POST',
  body: formData,
})
```
