Fixes #7802

[rohankmr414]

didn't remove the workflow/executor/k8sapi package as pns executor depends on it

argo-workflows/workflow/executor/pns/pns.go

Lines 29 to 49 in 1f1a1e0

	type PNSExecutor struct {
	*k8sapi.K8sAPIExecutor
	podName string
	namespace string
	// mu for `containerNameToPID``
	mu sync.RWMutex
	// mu for `pidFileHandles``
	pmu sync.RWMutex
	containerNameToPID map[string]int
	// pidFileHandles holds file handles to all root containers
	pidFileHandles map[int]*os.File
	// thisPID is the pid of this process
	thisPID int
	// rootFS holds a file descriptor to the root filesystem, allowing the executor to exit out of a chroot
