kubernetes: CI fails due to deprecated methods

[lucor]

Describe the bug:

After upgrading Kubernetes dependencies to version 2.6.x using Dependabot, the CI began failing due to the use of the following deprecated methods:

Error: internal/cloud/kubernetes.go:158:8: wait.PollImmediate is deprecated: This method does not return errors from context, use PollUntilContextTimeout. 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.  (SA1019)
Error: internal/cloud/kubernetes.go:221:8: exec.Stream is deprecated: use StreamWithContext instead to avoid possible resource leaks. See https://github.com/kubernetes/kubernetes/pull/103177 for details.  (SA1019)

They can be safely ignored, but it would be great to have them fixed.
