> Enrich Avro data source documentation to emphasize the difference between
> *avroSchema* which is an option, and *jsonFormatSchema* which is a parameter for function *from_avro* .
> When using {*}from_avro{*}, *avroSchema* option can be set to a compatible and evolved schema, while *jsonFormatSchema* has to be the actual schema. Elsewise, the behavior is undefined.
