aws_cdk_s3: enforce_ssl typo

### Describe the issue

enforce_ssl parameter has a typo in python documentation under aws_cdk_s3 module

Currently the documentation says:

bucket = s3.Bucket(self, "Bucket",
**enforce_sSL**=True
)

Correct Version:

bucket = s3.Bucket(self, "Bucket",
**enforce_ssl**=True
)

### Links

https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_s3/README.html

Open the linked AWS CDK v1 Python aws_cdk.aws_s3 README and find the Bucket example containing the enforce_sSL parameter. Correct the parameter spelling to enforce_ssl and verify that the example matches the documented API.
