[Bug]: hardly any completed TypeScript types

[tafelnl]

Expected Behavior

For this to be production ready I think it's fair to have at least the essential types like UserAddress, Product etc. implemented. Right now they are useless as they are all defined as unknown. As can be seen here: https://github.com/vuestorefront/shopify/blob/bc888047935e5979d3d1876bad965e5f3c2cb84c/packages/composables/src/types/index.ts

This makes it impossible to use @vue-storefront/shopify in a TypeScript environment. Which is a pity. A respectable storefront implemented in JavaScript should be type-safe in my opinion.

Are there any plans to tackle this?

Actual Behavior

No types present.

Implement the correct types.
