chose to go with 'y' / 'n' since getInput returns a string to keep it clearly non-boolean - but open to 'true' / 'false' or any preference of yours

I would like to use true/false here as it makes more sense. Understanding the limitation of core.getInput we can work around that making a comparison to the string of "true" when we make the call and that will convert it to the boolean.
