fix: remove GH_TOKEN from build steps to prevent electron-builder auto-publish

electron-builder auto-publishes when GH_TOKEN is set and running on a tag event.
This conflicts with softprops/action-gh-release handling the release.
Also skip code signing in CI with CSC_IDENTITY_AUTO_DISCOVERY=false.
