Switch from in- to excludes for resource inclusion

[lynxplay]

As nearly all resources found in the vanilla jar are desired to be
included in paper, an include list is not ideal. Instead, this commit
changes the copy resource tasks to an exclude-based filter.

Removed the extension as per jmp's suggestions. Consumers of paperweight hence may only edit this by directly editing the task.
I hope the map call is fine, as we don't need a flatMap to depend on anything.

as a sanity check, can you try to generate a before and after list of files that we include?

[lynxplay]

I'll generate a diff 👍

After building the re-obfuscated server using reobfJar for both paperweight 1.3.5 and this specific paperweight snapshot, extracting the output jar into old and new and running diff -r old/ new/ this is the output:

Only in new: flightrecorder-config.jfc
diff --color -r old/META-INF/MANIFEST.MF new/META-INF/MANIFEST.MF

The manifest changed as I stored my changes to paper to use paperweight in its own branch 👍
As expected the flight recorder is included.

nice, so no other files, perfect
