Bug: [OpenAPI] Upload file is not possible when defined as Optional
Description
When defining an UploadFile as Optional the upload file button disappears.
Removing the Optional makes the button to be present but there's no way not to specify the file anymore as there's no send empty value checkbox in this case.
