Update workshop.md
Running the first set of code that has defines the function ("def proportional_allocation_percentage(df, percentage):") runs well without any errors, but upon running the second set of code('percent = 0.05 .....'), an error is thrown (PySparkTypeError: [NOT_COLUMN_OR_STR] Argument col should be a Column or str, got float.). This happens due to errors in the first set of code that defines the function. I reviewed the code and made some adjustments that makes the code run without any errors.

@Jcardif could you review this one?
BTW we'd to either externalize in a separate repo or retire all workshops in the core (this) repo, could you think about that @Jcardif @cmaneu ? Thanks
Did anyone review? @Jcardif @cmaneu
