(aws_s3): CfnBucket.public_access_block_configuration property cannot be accessed

### What is the problem?

If you try to access the `public_access_block_configuration` property of a `CfnBucket` that is non-null, you get an error message from JSII.

https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_s3/CfnBucket.html#aws_cdk.aws_s3.CfnBucket.public_access_block_configuration

### Reproduction Steps

```python
from aws_cdk import (
aws_s3,
core
)

def main():
app = core.App()
env = core.Environment(region='us-east-1')
stack = core.Stack(app, 'cdk-test', env=env)
bucket = aws_s3.Bucket(stack, 'my-bucket', block_public_access=aws_s3.BlockPublicAccess.BLOCK_ALL)
app.synth()

print(bucket.node.default_child.public_access_block_configuration)

if __name__ == "__main__":
main()
```

### What did you expect to happen?

It should get the configuration without issue.

### What actually happened?

Start by running the Python reproduction against the jsii version in the report, then read jsii/_kernel/__init__.py and jsii/_reference_map.py around the failing interface lookup. Done means accessing CfnBucket.public_access_block_configuration no longer raises a KeyError for the PublicAccessBlockConfigurationProperty reference.
