Update json-data-type.md

In the "Limitations" section near the end of the document, it should read either of the following:

- The behavior of CAST ( ... AS JSON) returns a json type, but the sp_describe_first_result_set system stored procedure doesn't *correctly* return the json data type.

- The behavior of CAST ( ... AS JSON) returns a json type, but the sp_describe_first_result_set system stored procedure doesn't correct the returned json data type.

 ## Limitations
 
-- The behavior of `CAST ( ... AS JSON)` returns a **json** type, but the [sp_describe_first_result_set](../../relational-databases/system-stored-procedures/sp-describe-first-result-set-transact-sql.md) system stored procedure doesn't correct return the **json** data type. Therefore, many data access clients and driver will see a **varchar** or **nvarchar** data type.

   - Currently, TDS >= 7.4 (with UTF-8) sees **varchar(max)** with `Latin_General_100_bin2_utf8`.
   - Currently, TDS < 7.4 sees **nvarchar(max)** with database collation.
