(aws-config): Add support for s3-bucket-level-public-access-prohibited managed rule in ManagedRuleIdentifiers class

[sringel]

Description

Currently ManagedRuleIdentifiers doesn't support identifier for s3-bucket-level-public-access-prohibited managed rule (S3_BUCKET_LEVEL_PUBLIC_ACCESS_PROHIBITED). The documentation for this rule is here

Use Case

I should be able to create the s3-bucket-level-public-access-prohibited managed rule through CDK higher level construct.

Proposed Solution

Add constant to packages/@aws-cdk/aws-config/lib/rule.ts

  /**
   * Checks if Amazon Simple Storage Service (Amazon S3) buckets are publicly accessible. This rule is
   * NON_COMPLIANT if an Amazon S3 bucket is not listed in the excludedPublicBuckets parameter
   *  and bucket level settings are public.
   * @see https://docs.aws.amazon.com/config/latest/developerguide/s3-bucket-level-public-access-prohibited.html
   */
  public static readonly S3_BUCKET_LEVEL_PUBLIC_ACCESS_PROHIBITED = 'S3_BUCKET_LEVEL_PUBLIC_ACCESS_PROHIBITED';
