Determine if the azure reference in plugins/google/pubsub/topicEncryption.js is correct

The new Google pubsub encryption check includes a reference to an azure helper:

`const { call } = require('../../../helpers/azure/auth');`

I haven't tried running without it, but it seems odd that azure is referenced in a google check.

Apologies if this is intended, but it triggered my anal retentive tendencies.

Open plugins/google/pubsub/topicEncryption.js and inspect why it requires ../../../helpers/azure/auth. Compare that dependency with the Google Pub/Sub encryption check and review the referenced Azure helper. Done means the reference is confirmed as intentional or corrected, with the check still loading and running successfully.
