Rke2 shell completion

[vitorsavian]

Proposed Changes

• Add a completion for the shell the same way k3s does but with two more cli flags to add the kubectl and crictl to the environment

Types of Changes

• Feature

Verification

• Install rke2 and run rke2 completion bash -i --crictl --kubectl or rke2 completion zsh -i --crictl --kubectl

Testing

Linked Issues

• Add shell completion support to RKE2 #5488

User-Facing Change

RKE2 now support shell completion

Further Comments

• I saw the need for the entire Run function to be on RKE2 because the requirement for exposing kubectl and crictl files are only for rke2
