Version 9.6.1 breaks @google-cloud/pubsub's emulator mode

[alexanderczigler]

Environment details

• OS: linux
• Node.js version: 18
• npm version: 9
• google-auth-library version: 9.6.1

Steps to reproduce

1. Use @google-cloud/pubsub in a project
2. Run the project with PUBSUB_EMULATOR_HOST set (this tells the pubsub library it is connecting to an emulator, see https://cloud.google.com/pubsub/docs/emulator)
3. Note that the pubsub library fails with Error publishing to Pub/Sub Error: Could not load the default credentials.
4. Add "google-auth-library": "<9.6.1" to resolutions in package.json
5. Note that pusbusb now works together with the emulator as intended

Notes

The changes in 9.6.1 seem to have something to do with this.
