[SPARK-47942][K8S][DOCS] Drop K8s v1.26 Support
### What changes were proposed in this pull request?
This PR aims to update K8s docs to recommend K8s v1.27+ for Apache Spark
4.0.0.
This is a kind of follow-up of the following previous PR because Apache
Spark 4.0.0 schedule is delayed slightly.
- #43069
### Why are the changes needed?
**1. K8s community starts to release v1.30.0 from 2024-04-17.**
- https://kubernetes.io/releases/#release-v1-30
**2. Default K8s Version in Public Cloud environments**
The default K8s versions of public cloud providers are already K8s 1.27+.
- EKS: v1.29 (Default)
- GKE: v1.29 (Rapid), v1.28 (Regular), v1.27 (Stable)
- AKS: v1.27
**3. End Of Support**
In addition, K8s 1.26 is going to reach EOL when Apache Spark 4.0.0 arrives
because K8s 1.26 is also going to reach EOL on June.
| K8s | AKS | GKE | EKS |
| ---- | ------- | ------- | ------- |
| 1.26 | 2024-03 | 2024-06 | 2024-06 |
- [AKS EOL
Schedule](https://docs.microsoft.com/en-us/azure/aks/supported-kubernetes-versions?tabs=azure-cli#aks-kubernetes-release-calendar)
- [GKE EOL
Schedule](https://cloud.google.com/kubernetes-engine/docs/release-schedule)
- [EKS EOL
Schedule](https://docs.aws.amazon.com/eks/latest/userguide/kubernetes-versions.html#kubernetes-release-calendar)
### Does this PR introduce _any_ user-facing change?
- No, this is a documentation-only change about K8s versions.
- Apache Spark K8s Integration Test is currently using K8s v1.30.0 on
Minikube already.
### How was this patch tested?
Manual review.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #46168 from dongjoon-hyun/SPARK-47942.
