Fix RAM issue with deploy

A deploy was running the same max ram for both the pod and the java
app. This led to issues where the java app would use its max ram and the
pod would think it was out of memory. It would kill the pod and the
minecraft server with it, often not saving the last few minutes of
progress.

Now the deploy runs 1GiB extra ram than the java app.
