Subject: [PATCH] fix(desktop): use native fetch in the Electron main process

node-fetch is only a devDependency of @audius/web, so electron-builder
leaves it out of app.asar and the packaged app crashes on launch with
"Cannot find module 'node-fetch'" (#14745). Electron 33 ships Node 20,
which has fetch built in, so drop the require. The web-update download
now converts the web ReadableStream with Readable.fromWeb, since
.body.pipe() only exists on node-fetch responses, and skips the update
instead of writing an error page to disk when S3 returns a non-2xx.

Fixes #14745
