support k8s 1.32.2

rancher/rancher#48825

Changes:

1. Support k8s 1.32

Bump the k8s modules to 1.32.2
Bump the kubectl

2. Fix the broken e2e test cases

Failed tests:

 Job Generation when fails because of invalid time window should apply successfully after edit
 Job Generation when fails because of invalid post complete delay should apply successfully after edit

The initContainer is only set when plan.Spec.Prepare, plan.Spec.Cordon, or plan.Spec.Drain is not nil code, which doesn't seem to be the case for the plan created in these tests.

Seems like for some reason e2e was not running all the tests, but I'm not sure why. Logs for other recent PRs say:

For this PR we have:

@jiaqiluo can you merge or do you need me to do that?

@brandond, thanks for sharing the findings, that at least explains why the CI passed in the past.
I have the permission to merge PR and will do it once I get another approval from my team.
