When uploading to S3 please provide signed URLs in bindings

Describe the feature request When saving a file to an S3 bucket I can see that it has successfully been saved, but I would like the ability to display that file (where applicable) or use that file in a "Download File" action more easily. We should get back a signed URL as a binding from the Upload to S3 action step.

An example use-case would be using s3 buckets to store employee badge photos - a member of staff could upload the file, it could be fetched to display on that employee's profile page using the URL in an image, and downloaded by passing the URL to the download file action on a button.
