Fixes RnD experiment discounts applying indefinitely (#61258)

Discount experiments have been decreasing required points for nodes indefinitely, resulting in research costs being like Industrial Engineering here:

Curiously, this didn't mean free research points for reasons unknown to me.
I believe this has been going on for the entire lifespan of Experisci and nobody reported it. Yet here I am, an RnD main fixing something that's my lifeblood.

Discounts aren't supposed to grow into 1450%+ discounts over time.

RnD discount experiments now reduce the proper amount of points needed instead of gradually growing into a 100% free tech node.
