fix: set releaseType to release in electron-builder publish config

The release workflow creates a published GitHub release before
electron-builder runs. electron-builder defaults to releaseType=draft,
causing a type mismatch that prevents all asset uploads.

Setting releaseType to release tells electron-builder to upload assets
to the existing published release.
