chore: adding Java 25 for paper

[DEV-DIBSTER]

Description

Adding Java 25 to the Paper Egg (PaperMC) under minecraft/java/paper.

The docker container that is being added is the ghcr.io/pterodactyl/yolks:java_25.

This is needed as Minecraft after Minecraft 26.1 Snapshot 1 will require Java 25 (source here).
