Remove shaded SLF4J to fix STDERR spam on modern servers

Paper already provides SLF4J with a working provider. Shading and
relocating slf4j-nop broke ServiceLoader discovery, causing
"No SLF4J providers were found" warnings on every startup.

Changed slf4j-nop from implementation to compileOnly slf4j-api and
removed it from shadow includes/relocations.
