### Description

Airflow provides the Amazon DynamoDB to Amazon S3 below.  
https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/operators/transfer/dynamodb_to_s3.html

Most of Data Engineer build their "export DDB data to s3" pipeline using "within the point in time recovery window".   
https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/dynamodb.html#DynamoDB.Client.export_table_to_point_in_time

I appreciate if airflow has this function as a native function.  

### Use case/motivation

My daily batch job exports its data with pitr option. All of tasks is written by apache-airflow-providers-amazon except "export_table_to_point_in_time" task. 
"export_table_to_point_in_time" task only used the python operator. I expect I can unify the task as apache-airflow-providers-amazon library.

"""
    Replicates records from a DynamoDB table to S3.
    It scans a DynamoDB table and writes the received records to a file
    on the local filesystem. It flushes the file to S3 once the file size
    exceeds the file size limit specified by the user.
    Users can also specify a filtering criteria using dynamodb_scan_kwargs
    to only replicate records that satisfy the criteria.
