Add EDI samples to Stedi guides

EDI sample files convey pages worth of specifications in a single snapshot. They help new trading partners understand valid usage patterns faster and reduce debugging time.

You can now add up to five EDI samples in each Stedi guide to represent supported variants. The guide builder automatically validates new sample files against the guide specifications, so you can fix errors before providing them to your trading partners.

After you add samples, your trading partners can view and edit them directly in their web browsers.
