fix(release): exclude etherpad/bin/ from extraResources to unbreak Win (#51)

The v0.4.2 release build cleared deb / snap / macOS / AppImage but
release-windows still failed. The 7za scan reports many warnings:

  .\resources\etherpad\bin\node_modules\ep_etherpad-lite\node_modules\async\
  : The system cannot find the path specified.
  (and the same for cookie-parser, cross-env, cross-spawn, ejs, esbuild,
   express, express-rate-limit, express-session, find-root, formidable,
   http-errors, jose, js-cookie, jsdom, jsonminify, jsonwebtoken, ...)

7za exits 1 on warnings, electron-builder treats that as a build
failure, and the NSIS .exe never gets produced.

Etherpad's `bin/` directory is operator CLI utilities (compactPad,
importSqlFile, migrateDB, etc.) that the embedded server never
invokes at runtime. Its package.json declares a workspace symlink to
`../src`, and the nested
  bin/node_modules/ep_etherpad-lite/node_modules/<dep>
paths are pnpm symlinks. Tar preserves them on extract; Linux/macOS
follow them, Windows can't.

Exclude `bin/**` from extraResources — findBundledEtherpadDir +
node/server.ts only need `src/`.
