Add @aws-sdk/client-sts dependency

[abhandage]

Currently when I am running the tests after upgrading dependencies in integrations I am facing below error

  ✖ No tests found in Service/service.test.js

  Uncaught exception in Service/service.test.js

  Error: Cannot find module '@aws-sdk/client-sts'

Because @aws-sdk/client-sts has not been added as a directly dependency in actions-destinations.

Hence adding it here.

Pull Request Overview

This PR addresses a missing dependency issue by adding @aws-sdk/client-sts as a direct dependency to fix module resolution errors in tests. The AWS STS client is being used in the AWS S3 destination but was not declared as a dependency, causing runtime errors when other packages try to import the action-destinations library.

Key Changes

• Added @aws-sdk/client-sts version 3.614.0 to the package.json dependencies
