Code Review

This pull request upgrades @google-cloud/pubsub from version 0.20.0 to 4.0.0 to address security vulnerabilities. While this is a necessary security update, this is a major version upgrade that introduces significant breaking changes. The existing sample code that relies on this package has not been updated and will likely break. The pull request should be amended to include the necessary code modifications in the sample files to ensure they are compatible with the new version of the library.

[gemini-code-assist]

Upgrading from version 0.20.0 to 4.0.0 is a major version jump that introduces significant breaking changes. The sample code in this repository that uses @google-cloud/pubsub will likely fail to run with this new version.

For example, one common breaking change in Google Cloud libraries is the switch to named exports for client classes. The existing code likely uses const PubSub = require('@google-cloud/pubsub');, which would need to be updated to const {PubSub} = require('@google-cloud/pubsub');.

Other API methods and their return values may have also changed. To ensure the samples remain functional, please update the JavaScript files in the samples/ directory (such as quickstart.js, subscriptions.js, and topics.js) to be compatible with @google-cloud/pubsub v4.0.0.
