Docs: Idempotency - `Exception not affecting idempotency record sample` example has python syntax errors

[michaelbrewer]

Expected Behaviour

Handling exceptions - Exception not affecting idempotency record sample example should not have python syntax errors or missing imports.

Current Behaviour

This example have python syntax errors and missing imports

Code snippet

def lambda_handler(event, context):
    # If an exception is raised here, no idempotent record will ever get created as the
    # idempotent function does not get called
    do_some_stuff()

    result = call_external_service(data={"user": "user1", "id": 5})

    # This exception will not cause the idempotent record to be deleted, since it
    # happens after the decorated function has been successfully called
    raise Exception


@idempotent_function(data_keyword_argument="data", config=config, persistence_store=dynamodb)
def call_external_service(data: dict, **kwargs):
    result = requests.post('http://example.com', json={"user": data['user'], "transaction_id": data['id']}
    return result.json()

Possible Solution

Fix python syntax errors like the PR #1119 , and deployed over here https://gyft.github.io/aws-lambda-powertools-python/latest/utilities/idempotency/#handling-exceptions

import requests

from aws_lambda_powertools.utilities.idempotency import DynamoDBPersistenceLayer, IdempotencyConfig, idempotent_function

dynamodb = DynamoDBPersistenceLayer(table_name="idem")
config = IdempotencyConfig(event_key_jmespath="order_id")


def lambda_handler(event, context):
    # If an exception is raised here, no idempotent record will ever get created as the
    # idempotent function does not get called
    do_some_stuff()

    result = call_external_service(data={"user": "user1", "id": 5})

    # This exception will not cause the idempotent record to be deleted, since it
    # happens after the decorated function has been successfully called
    raise Exception


@idempotent_function(data_keyword_argument="data", config=config, persistence_store=dynamodb)
def call_external_service(data: dict, **kwargs):
    result = requests.post("http://example.com", json={"user": data["user"], "transaction_id": data["id"]})
    return result.json()

Steps to Reproduce

1. Go to https://awslabs.github.io/aws-lambda-powertools-python/latest/utilities/idempotency/#handling-exceptions
2. Copy Exception not affecting idempotency record sample
3. Code example should not be able to compile
