Remove deprecated cloudfront_origins.S3Origin from static site example

[zeekrey]

Describe the bug

The static site example utilizes

origin: new cloudfront_origins.S3Origin(siteBucket, {originAccessIdentity: cloudfrontOAI}),

even though S3Origin is labeled as deprecated: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront_origins.S3Origin.html

Expected Behavior

The example uses S3BucketOrigin or S3StaticWebsiteOrigin instead.

Current Behavior

Using the example triggers a deprecation warning.

Reproduction Steps

Checkout https:/aws-samples/aws-cdk-examples/blob/main/typescript/static-site/static-site.ts and install latest deps.
