### What changes were proposed in this pull request?
This PR aims to update K8s docs to recommend K8s v1.32+ at Apache Spark
4.1.0 to utilize more stable features like the following example features
graduated to `Stable` at K8s v1.32.
- [KEP-1847: Auto remove PVCs created by
StatefulSet](https://github.com/kubernetes/enhancements/issues/1847)
- [KEP-1967: Support to size memory backed
volumes](https://github.com/kubernetes/enhancements/issues/1967)
- [KEP-4358: Custom Resource field
selectors](https://github.com/kubernetes/enhancements/issues/4358)
### Why are the changes needed?
**1. K8s v1.31 will enter the maintenance soon (2025-08-28) and will reach
the end of support on 2025-10-28**
- https://kubernetes.io/releases/patch-releases/#1-31
**2. Default K8s Versions in Public Cloud environments**
The default K8s versions of public cloud providers are already moving to
K8s 1.32+ like the following.
- EKS: v1.32 (Default), v1.33 (Available)
- AKS: v1.32 (Default), v1.33 (GA)
- GKE: v1.32 (Stable), v1.32 (Regular), v1.33 (Rapid)
**3. End Of Support**
In addition, K8s 1.31 will reach the end of standard support around Apache
Spark 4.1.0 release.
