Adds diet Diesel to the Diona loadout (#20897)

Formerly called "decaf Diesel". Sprite for the diet Diesel jar created
by me.

Diet Diesel, created by the HPV Narrows and sponsored by Hephaestus
Industries! It'll give you that energizing effect without any of that
radiation that's dangerous to other species. ~Still toxic to
non-Dionae.~
