Please provide a summary of what's being changed

This PR changes the access modifier of the getHashedIdempotencyKey() method in the packages/idempotency/src/persistence/BasePersistenceLayer.ts class so that customers can extend it and provide their own implementation for how the idempotency key is created.

import { DynamoDBPersistenceLayer } from '@aws-lambda-powertools/idempotency/dynamodb';
import type { JSONValue } from '@aws-lambda-powertools/commons/types';

class MyOwnPersistenceLayer extends DynamoDBPersistenceLayer {
  getHashedIdempotencyKey(data: JSONValue): string {
    return 'foo'; // this string will be used as idempotency key - use with caution
  }
}

// use MyOwnPersistenceLayer as you would DynamoDBPersistenceLayer

As with all the protected methods, you are free to extend the method in your own codebase but we don't guarantee stability of these methods.
