chore: Use "true" instead of "y" when setting variables

While "y" may usually be accepted as a valid boolean value, "true" is more standard and meaningful.

To be fair, the actual value of the variables doesn't matter as I use conditionals based on whether the variable is empty or not.
Still, "true" is more conventional.
