The latest CNG kubectl image contains an invalid binary
Looks like the download was not successful and returned an unexpected content. See:
$ docker run --rm registry.gitlab.com/gitlab-org/build/cng/kubectl cat /usr/local/bin/kubectl
<?xml version='1.0' encoding='UTF-8'?><Error><Code>NoSuchKey</Code><Message>The specified key does not exist.</Message><Details>No such object: kubernetes-release/release//bin/linux/amd64/kubectl</Details></Error>
