(FIRST 1.16.3): Update Paper to 1.16.3
This is a pretty tiny update with very little changed. Recommended to update
from 1.16.2 ASAP as 1.16.2 is now no longer supported.

Plugins should mostly remain working as the NMS revision did not change.

Subject: [PATCH] Do less work if we have a custom Bukkit generator
If the Bukkit generator already has a spawn, use it immediately instead
of spending time generating one that we won't use
