Fix fabric.mod.json versioning

[Ranzeplay]

Due to the incorrect Minecraft version description, the server fails to start.

Starting net.fabricmc.loader.impl.game.minecraft.BundlerClassPathCapture

[10:12:10] [main/ERROR]: Incompatible mods found!
net.fabricmc.loader.impl.FormattedException: Some of your mods are incompatible with the game or each other!
A potential solution has been determined, this may resolve your problem:
         - Replace mod 'Architectury' (architectury) 17.0.4 with any version that is compatible with:
                 - minecraft 1.21.6
More details:
         - Mod 'Architectury' (architectury) 17.0.4 requires version 1.21.6~ of 'Minecraft' (minecraft), but only the wrong version is present: 1.21.6!

So we fix the description so that it can start.
