chore: make version auto-generate in publish-socketbin workflow

Make the version input optional and auto-generate it from current UTC
timestamp (YYYY.MM.DD.HHmmss format) if not provided. Users can still
provide a custom version if needed. This reduces friction when
publishing binaries without having to manually enter the datetime.
