feat(bedrock): add support for os managed cluster and guardrails latest properties

[krokoko]

Fixes #1092

• Upgrades base cdk version to v2.191.0
• Add new properties added to guardrails in aws/aws-cdk@adfa416 . /!\ This has some breaking changes due to additional props for Word and ManagedWord filters.
• Add new prop TextIndexName for MongoDBAtlas
• Add support for OpenSearch Managed cluster in KB as a vector store

Testing:

• tested guardrails with the following code snippet:

const guardrail = new bedrock.Guardrail(this, 'bedrockGuardrails', {
      name: 'my-BedrockGuardrails',
      description: 'Legal ethical guardrails.',
    });

    guardrail.addContentFilter({
      type: bedrock.ContentFilterType.SEXUAL,
      inputStrength: bedrock.ContentFilterStrength.HIGH,
      outputStrength: bedrock.ContentFilterStrength.MEDIUM,
      inputAction: bedrock.GuardrailAction.BLOCK,
      inputEnabled: true,
      outputAction: bedrock.GuardrailAction.NONE,
      outputEnabled: true,
      inputModalities: [bedrock.ModalityType.TEXT, bedrock.ModalityType.IMAGE],
      outputModalities: [bedrock.ModalityType.TEXT],
    });

    guardrail.addDeniedTopicFilter(bedrock.Topic.FINANCIAL_ADVICE);

    guardrail.addDeniedTopicFilter(
      bedrock.Topic.custom({
        name: 'Legal_Advice',
        definition: 'Offering guidance or suggestions on legal matters, legal actions, interpretation of laws, or legal rights and responsibilities.',
        examples: [
          'Can I sue someone for this?',
          'What are my legal rights in this situation?',
          'Is this action against the law?',
          'What should I do to file a legal complaint?',
          'Can you explain this law to me?',
        ],
        inputAction: bedrock.GuardrailAction.BLOCK,
        inputEnabled: true,
        outputAction: bedrock.GuardrailAction.NONE,
        outputEnabled: true,
      })
    );

    guardrail.addManagedWordListFilter({
      type: bedrock.ManagedWordFilterType.PROFANITY,
      inputAction: bedrock.GuardrailAction.BLOCK,
      inputEnabled: true,
      outputAction: bedrock.GuardrailAction.NONE,
      outputEnabled: true,
    });
    
    // Add individual words
    guardrail.addWordFilter({text: 'drugs'});
    guardrail.addWordFilter({text: 'competitor'});

    guardrail.addWordFilter({
      text: 'violence',
      inputAction: bedrock.GuardrailAction.BLOCK, 
      inputEnabled: true, 
      outputAction: bedrock.GuardrailAction.NONE, 
      outputEnabled: true
    });

    guardrail.addPIIFilter({
      type: bedrock.PIIType.General.ADDRESS,
      action: bedrock.GuardrailAction.BLOCK,
      inputAction: bedrock.GuardrailAction.BLOCK,
      inputEnabled: true,
      outputAction: bedrock.GuardrailAction.ANONYMIZE,
      outputEnabled: true,
    });
    
    // Add PII filter for credit card numbers with input/output actions
    guardrail.addPIIFilter({
      type: bedrock.PIIType.General.LICENSE_PLATE,
      action: bedrock.GuardrailAction.BLOCK,
      inputAction: bedrock.GuardrailAction.BLOCK,
      inputEnabled: true,
      outputAction: bedrock.GuardrailAction.ANONYMIZE,
      outputEnabled: true,
    });

    guardrail.addRegexFilter({
      name: 'TestRegexFilter',
      description: 'This is a test regex filter',
      pattern: '/^[A-Z]{2}d{6}$/',
      action: bedrock.GuardrailAction.ANONYMIZE,
      inputAction: bedrock.GuardrailAction.BLOCK,
      inputEnabled: true,
      outputAction: bedrock.GuardrailAction.ANONYMIZE,
      outputEnabled: true,
    });

    guardrail.addContextualGroundingFilter({
      type: bedrock.ContextualGroundingFilterType.GROUNDING,
      action: bedrock.GuardrailAction.BLOCK,
      enabled: true,
      threshold: 0.8,
    });

Deploys and works as expected
