[dynamodb] resource is not synced, when Spec.AttributeDefinitions not sorted by ascii code order in manifest

[Julian-Chu]

Describe the bug
when Spec.AttributeDefinitions are not sorted by ascii code, the resource is not synced.

Steps to reproduce

apiVersion: dynamodb.services.k8s.aws/v1alpha1
kind: Table
metadata:
  name: ack-demo
spec:
  keySchema:
    - attributeName: id
      keyType: HASH
    - attributeName: externalId
      keyType: RANGE
  attributeDefinitions:
    - attributeName: id
      attributeType: S
    - attributeName: externalId
      attributeType: S
  provisionedThroughput:
    readCapacityUnits: 1
    writeCapacityUnits: 1
  tableName: "ack-demo-table"

log from controller
2022-12-19T12:32:16.641Z INFO ackrt desired resource state has changed {"account": "*******", "role": "", "region": "eu-west-1", "kind": "Table", "namespace": "default", "name": "ack-demo", "is_adopted": false, "generation": 1, "diff": [{"Path":{"Parts":["Spec","AttributeDefinitions"]},"A":[{"attributeName":"id","attributeType":"S"},{"attributeName":"externalId","attributeType":"S"}],"B":[{"attributeName":"externalId","attributeType":"S"},{"attributeName":"id","attributeType":"S"}]}]}

format json:

{
  "account": "*********",
  "role": "",
  "region": "eu-west-1",
  "kind": "Table",
  "namespace": "default",
  "name": "ack-demo",
  "is_adopted": false,
  "generation": 1,
  "diff": [
    {
      "Path": {
        "Parts": [
          "Spec",
          "AttributeDefinitions"
        ]
      },
      "A": [
        {
          "attributeName": "id",
          "attributeType": "S"
        },
        {
          "attributeName": "externalId",
          "attributeType": "S"
        }
      ],
      "B": [
        {
          "attributeName": "externalId",
          "attributeType": "S"
        },
        {
          "attributeName": "id",
          "attributeType": "S"
        }
      ]
    }
  ]
}

Expected outcome
resource should be synced.

Environment

Kubernetes version: 1.23
EKS: 1.23
