This pull request addresses

A build failure in the CI/CD pipeline caused by Webpack 5 no longer including polyfills for Node.js core modules (http, https) by default. The eventsource library (dependency of @webex/cc-digital-channels) requires these modules, causing the cc-widgets package build to fail with "Module not found" errors.

by making the following changes

Added resolve.fallback configuration in packages/contact-center/cc-widgets/webpack.config.js to set http: false and https: false, instructing webpack to ignore these Node.js-specific modules since browsers have native EventSource API support.
