Update InstantDamage and Regeneration values

Introduction

While working on #5276 I realized that were outdated.

Tests

Data were obtained from https://minecraft.fandom.com/wiki/Potion and has been play-tested to match with vanilla

So, I've looked into this and the changes to Instant Damage look good and match both the wiki as well as in-game.
But while checking the wiki page of the regeneration effect, I noticed this: Amplifiers outside the range 0–31 (corresponding to levels 1–32) are used modulo 32, making level 33 the same as level 1, etc.
I know, that we don't aim for bug parity here, but I am not sure whether this counts as a bug and should be left as is in the code or modified to match Mojangs weird behaviour.

I don't think it matters. No one will notice anyway, and if someone does try to use such a high level, they'll think the modulo behaviour itself is a bug.
