[jl4nz]

Adds optional filter and optional overrideSearchType parameters to the Bedrock knowledge base client:

export interface AmazonKnowledgeBaseRetrieverArgs {
  knowledgeBaseId: string;
  topK: number;
  region: string;
  clientOptions?: BedrockAgentRuntimeClientConfig;
  filter?: RetrievalFilter;
  overrideSearchType?: SearchType;
}

Also, updates the source location of the document depending on the KB configuration: S3, WEB, CONFLUENCE, SALESFORCE, SHAREPOINT

Hey there! 👋 I noticed that this PR includes a change in the dependencies, specifically the update of "@aws-sdk/client-bedrock-agent-runtime" and "@aws-sdk/types". This is flagged for maintainers to review as it affects the peer/dev dependencies of the project. Keep up the great work! 🚀

Thanks for the review and merge @bracesproul. Is it possible to bump the aws package? or there's a release process/waiting?
