Request: Provide URL of deployed site

[bu-ra3y]

using version: 4.0.0-rc3

First off, thank you for this package!

A feature request:
I would like the deploy script to output the URL at which I can load my site.

A url is mentioned during deploy but it's not the one needed to load the site.
INFO Deploying 39 assets from /Users/<user>/project/web/dist/ to https://s3-us-east-1.amazonaws.com/<bucket>/

In this case the site can be loaded at:
https://s3.amazonaws.com/<bucket>/index.html
rather than:
https://s3-us-east-1.amazonaws.com/<bucket>/

Good idea! :)
