Farmers sell suspicious stews with 20 times the intended duration

The expert level farmer sells Night Vision, Jump Boost, Weakness, Blindness, and Poison suspicious stews with 20 times the duration of those sold in 1.21.11. This is due to the set_stew_effect function multiplying the specified durations of non-instant effects by 20, so the durations specified are 20 times too long for all effects except Saturation.
