Fix: kube-apiserver tag will overwrite secrets-at-rest token if used independently

[jwitko]

What type of PR is this?
/kind bug

What this PR does / why we need it:
If a user runs update-cluster.yml with tag kube-apiserver the playbook will not check whether or not the secrets-at-rest encryption token is already defined and will instead generate a new token and replace it potentially rendering secrets into an inaccessible and unrecoverable state.

This PR applies the tag to all tasks in the file as they are all needed to properly determine the course of action.

Which issue(s) this PR fixes:
Fixes #10459

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

Hi @jwitko. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
