fix(release): drop custom electronDist so CI packs clean electron dist

The explicit electronDist=node_modules/electron/dist made electron-builder
deep-copy pnpm's symlinked store as the Electron distribution. On CI runners
that copy dropped electron.exe, so the productName rename failed with ENOENT.
Removing it lets electron-builder fetch/unpack the detected electron version
from its own cache (the standard, pnpm-safe path). Also add shell
description/author to silence packaging metadata warnings.
