Type of sourceProducts property in Card (Deck) data model

[grim7reaper]

Location of update needed

Card (Deck)

What does the documentation look like?

A list of associated Sealed Product uuid properties where this card can be found in.
- Type: `string[]`
- Introduced: `v5.2.2`

What should the documentation look like?

Not 100% sure. On one hand it's clearly not a list of Sealed Product uuid, it looks like more a Source Products object. On the other hand, properties of Source Products are non-optional but we sometimes have only one here. So maybe we should update the Source Products documentation as well?

Example with the card Tetravus from AzaarLichlord_PAST.json, where foil is missing:
