Download worker isn't deterministic

So now that workers store multiple files, this API fetches them as one text block using Content-Disposition segments for each file. However, the output appears to not sort them. So the output can change from request to request as the files are returned in seeming random order–even when there are no changes to the worker.

Please consider sorting the output by file name:{account_identifier}/workers/scripts/{script_name}

And the undocumented–but better:{account_identifier}/workers/services/{script_name}/environments/{worker_env}/content
