(aws-eks): `KubernetsPatch`'s applyPatch, restorePatch type is incorrect when 'PatchType.JSON'

Json Patch standard denotes that https://tools.ietf.org/html/rfc6902#section-3

> A JSON Patch document is a JSON [RFC4627] document that represents an
> array of objects. Each object represents a single operation to be
> applied to the target JSON document.

However `KubernetesPatch.applyPatch` type is `{ [key: string]; any }`.
https://github.com/aws/aws-cdk/blob/master/packages/%40aws-cdk/aws-eks/lib/k8s-patch.ts#L20-L28

It is not wrong, but somewhat confusing.

### Reproduction Steps

### What did you expect to happen?

it should be `{ [key: string]; any} | {op: "add"|"remove"|"replace"|"move"|"copy"|"test", path: string, value: any}[]`

### What actually happened?

### Environment

- **CDK CLI Version :** 1.75.0
- **Framework Version:** 1.75.0
- **Node.js Version:**
- **OS :**
- **Language (Version):**

This is :bug: Bug Report

Start in packages/@aws-cdk/aws-eks/lib/k8s-patch.ts, especially the applyPatch and restorePatch type definitions, and compare them with the JSON Patch format described in RFC 6902 section 3. Done means the public types accurately represent JSON Patch operations while preserving the existing patch form.
