A string range query on a JSON field should return an error

If you have a JSON field field in your mapping and you make a range query field.subfield:[y TO z] will match all the documents.

Instead, we should return an error.

I think the problem is introduced by this snippet

Maybe we can output an error such as

return Err(InvalidQuery::RangeQueryNotSupportedForBoundary {
                    field_name: field_entry.name().to_string(),
                    boundaries 
                });
