install remapped server jar to paper package space
Spigot has been stripping the minecraft-server jar down in order to
reduce it's size, primarily by removing classes they don't use from
fastutil. as we use fastutil and offer it as API, this is useless
to us, and creates headaches when it breaks builds due to spigots
version of this being installed.
