Issue #, if available:

Description of changes:
Check that CLI examples use approved placeholders and fix existing violations

Rules from the "Sanitizing sensitive information" section of the Style guide:

1. "Sanitize your examples. Replace all sensitive information with placeholders such as:"
2. "Account IDs: 123456789012. If your example requires multiple account IDs, then use this pattern: 123456789111, 123456789222, 123456789333, …"
3. "GUIDs: a1b2c3d4-5678-90ab-cdef-EXAMPLE11111. If your example requires multiple GUIDs, then use this pattern: a1b2c3d4-5678-90ab-cdef-EXAMPLE22222, a1b2c3d4-5678-90ab-cdef-EXAMPLE33333, …"
4. "Regions: us-west-2. Unless the resource can only exist in a different region."
5. "Bucket names: amzn-s3-demo-bucket. If your example requires multiple buckets, then use this pattern: amzn-s3-demo-bucket1, amzn-s3-demo-bucket2, amzn-s3-demo-bucket3, …"

• Added test_example_sanitization to tests/functional/docs/test_examples.py:
  • Account IDs, GUIDs, bucket names (in s3://, S3 ARNs, --bucket, and "Bucket" keys) and regions must use the approved placeholders.
  • Examples that use two or more regions (for example a cross-region copy or a DynamoDB global table) are not checked for regions.
  • Digits inside longer IDs (such as ami-066877671789bd71b) and S3 access point URIs (s3://arn:...) are not flagged.
• Replaced account IDs, GUIDs, bucket names and regions with the approved placeholders in 2455 example files, keeping related values consistent:
  • Availability Zones match the new region.
  • Cross-account examples use a second account (123456789111).
  • Lists that would repeat a region after the change were deduplicated.
• Examples that need a real value are listed per example in example_style_exceptions.json (92 examples), each with its reason:
  • Resources that only exist in one region, such as CloudFront certificates and global WAF web ACLs, and the ECR Public, Route 53 Domains and Cost and Usage Report APIs (all us-east-1)
  • AWS-owned accounts, such as the Amazon AMI owner, Inspector rules packages and the predefined patch baselines
  • AWS-owned buckets, such as the EMR sample bucket, CodeDeploy agent buckets and the GameLift build bucket
  • Fixed IDs, such as the AWS managed CloudFront cache policy ID and the DRM SystemId

Testing

• Run pytest tests/functional/docs/test_examples.py -n auto
