[Bug] Docs have very old, invalid info for Karpenter

[omkensey]

What were you trying to accomplish?

eksctl Karpenter docs should be up to date.

What happened?

The current docs refer to very old versions of Karpenter and EKS and resource types that are no longer valid.

Anything else we need to know?
The current docs refer to a no-longer-supported version of EKS (1.24), a very old version of Karpenter (0.20.0), and a Karpenter resource type (Provisioner) that no longer exists in the current Karpenter API (Provisioners were deprecated in Karpenter 0.32 and removed with the transition to v1beta1 API in 0.33). This was previously reported in #7482 but that issue went stale and was eventually auto-closed without resolution. Since the eksctl docs for installing Karpenter continue to be referred to up to the current time, it would be helpful to have an updated version.
