Update GitHub Actions to latest versions and improve release workflow

Upgraded actions/checkout, actions/cache, and game-ci/unity-builder to v4 in build and package workflows. Updated release workflow to use softprops/action-gh-release for creating releases and uploading assets, replaced deprecated set-output commands with GITHUB_OUTPUT, and set explicit permissions. Also updated github-push-action to a tagged version for improved reliability.
