Use non-deprecated functions after K8s lib bump

Go linter errors [1] suggested to use different functions, so use them to
appease the robots. But also mostly because the K8s developers have
decided to deprecate the existing functions

[1]:

```
Error: SA1019: wait.PollWithContext is deprecated: This method does not return errors from context, use PollWithContextTimeout. Note that the new method will no longer return ErrWaitTimeout and instead return errors defined by the context package. Will be removed in a future release.  (staticcheck)
```
