Completion subcommand for kubectl-accurate

[ymmt2005]

What

This is not possible for the time being.
This is possible with Kubernetes 1.26 or better.

spf13/cobra can auto-generate shell completion rules, so add completion
subcommand to kubectl-accurate for Bash, Zsh, PowerShell, Fish, etc.

Note that it should work when invoked as kubectl accurate ....
