feat: inject GH_TOKEN for electron-builder publishing

Added GH_TOKEN secret injection to all build jobs in the release
workflow. This allows electron-builder to automatically publish
release artifacts to GitHub when a git tag is detected.

Changes:
- Added GH_TOKEN environment variable to build-linux job
- Added GH_TOKEN environment variable to build-windows job
- Added GH_TOKEN environment variable to build-macos-x64 job
- Added GH_TOKEN environment variable to build-macos-arm64 job
- Removed publish: [] from electron-builder config to allow auto-publishing

The GH_TOKEN secret needs to be configured in GitHub repository
settings for this to work.
