Add `--merge` flag to `k3sup plan` command

[DaruZero]

Why do you need this?

I use the plan command to automate bootstrapping many clusters, and it would be useful to add --merge flag to the resulting script in order to avoid manually merging the kubeconfig.

Expected Behaviour

Running the bootstrap script should require as little additional steps as possible.

Current Behaviour

After bootstrapping a cluster, I need to manually merge the new kubeconfig with the default one

Possible Solution

Add the --merge flag to the plan command, that would simply add the same --merge flag to the install command in the generated bootstrap script
