New translatable boolean field for Metafield GraphQL Object

API version 2026-10 adds a non-null translatable field to the Metafield object in the GraphQL Admin API. Apps that fetch translatable metafields and migrate to 2026-10 can now see whether a metafield’s value is translatable directly on the metafield itself. If your app doesn’t query for translatable metafields by shop, you don’t need to change anything.
