Refactored Dataframe join comment to use correct parameter ordering
The API signatire for join requires the JoinType to be the third parameter.
The code examples provided for join show JoinType being provided as the 2nd
parater resuling in errors (i.e. "df1.join(df2, "outer", $"df1Key" ===
$"df2Key") ). The correct sample code is df1.join(df2, $"df1Key" === $"df2Key",
"outer")
