Docs and playground disagree about where version gets added to index.

Describe the bug

The docs say that the version get added to the primary key when using composite indices, but in playground is gets added to the sort key.

Entity/Service Definitions
Include your entity model (or a model that sufficiently recreates your issue) to help troubleshoot.

const stores = new Entity({
  model: {
    entity: "stores",
    service: "malldirectory",
    version: "1"
  },
  attributes: {
    storeId: {
      type: "string",
      label: "sid",
    },
    mallId: {
      type: "string",
      label: "mid",
    },
    buildingId: {
      type: "string",
      label: "bid",
    },
    unitId: {
      type: "string",
      label: "uid",
    }
  },
  indexes: {
    locations: {
      pk: {
        field: "pk",
        composite: ["storeId"]
      },
      sk: {
        field: "sk",
        composite: ["mallId", "buildingId", "unitId"]
      }
    }
  }
}, { table: "your_table_name" });

Expected behavior
Docs say the indexes should look like

  "pk": "$mallstoredirectory_1#sid_storevalue",
  "sk": "$mallstores#mid_mallvalue#bid_buildingvalue#uid_unitvalue"

But playground has

        "pk": "$malldirectory#sid_storevalue",
        "sk": "$stores_1#mid_mallvalue#bid_buildingvalue#uid_unitvalue"

Docs have the version on the primary key, but playground has the version on the sort key. Which is the actual production behavior?
