### What You Are Seeing?
When using Script Builder with multiple packages, and trying to use the "Download Packages" button on Step 4 of the modal (any integration method other than Individual), it only triggers one package to download.

### What is Expected?
Behind the scenes, this is trying to download multiple files at once. This is often not allowed or blocked by the browser. We should instead look to zip up these files and serve a final .zip file instead.

### How Did You Get This To Happen?
1. Add multiple (at least 2) packages to Script Builder.
1. Open the modal and choose any integration method other than individual.
1. On Step 4, expand "Option 1" or "Option 2" and click the "Download Packages" button.
1. Notice how only 1 package is downloaded, and not all the packages that are in Script Builder.
