SHA512 incorrect on most/many releases

Report Submission Form ## Summary: SHA512 is incorrect for most versions of kubernetes.tar.gz releases (https://github.com/kubernetes/kubernetes/releases/). ## Kubernetes Version: all ## Component Version: all ## Steps To Reproduce: [add details for how we can reproduce the issue, including relevant cluster setup and configuration] curl -sLO https://github.com/kubernetes/kubernetes/releases/download/v1.20.0/kubernetes.tar.gz shasum -a 512 kubernetes.tar.gz (mac) openssl dgst -sha512 kubernetes.tar.gz (linux) sha512sum kubernetes.tar.gz (linux) All report: ebfe49552bbda02807034488967b3b62bf9e3e507d56245e298c4c19090387136572c1fca789e772a5e8a19535531d01dcedb61980e42ca7b0461d3864df2c14 Per website, it should be: cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0ff8318d2877eec2f63b931bd47417a81a538327af927da3e ## Supporting Material/References: https://github.com/kubernetes/kubernetes/releases/tag/v1.20.0 another example: https://github.com/kubernetes/kubernetes/releases/tag/v1.19.5 Same SHA512: cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0ff8318d2877eec2f63b931bd47417a81a538327af927da3e ## Impact I suspect its an automation release issue (hence same hash in all places). * Impact 1: Can't verify artifact is correct artifact. * Impact 2: Hacked?
