Generated kubelet reference for v1.34

We have been unable to generate reference for kubelet for a loooong
time, due to a disruptive refactoring that happened to the upstream
source. With the help from soltysh, we are now able to generate it
again. This means we don't have to manually sync this command line
reference any more.
