Rubidium-Aether Chunk Fix 1.19.4

Install this instead of regular Rubidium 0.6.4 for MC 1.19.4 with The Aether to fix the chunk rendering glitch.

Current 1.19.4-dev build of Rubidium 0.6.4 as of 8/28/2023 that includes PR #475, a fix for chunk loading when The Aether is also installed. bipsydev built it so you don't have to! Thanks to bconlon1 for making this fix!

Rubidium is a Unofficial Fork of the Sodium maked to work on FML.
