Environment details

• OS: Mac
• Node.js version: v22.5.1
• npm version: 10.8.2
• @google-cloud/firestore version: 7.11.0

Steps to reproduce

1. Call the method listDocuments on a collection
2. Check your logs to see warning
   I've created a test repo to easily reproduce: https://github.com/Damotech/firestore-list-documents-warning

This isn't a major issue, we noticed it recently through the use of firebase-admin/firestore. In our production environment we are seeing them as errors so we get alerted about them once in a while. Though running the test-repo code alone, we are seeing them as warnings.

The warning stems from another lib, here is the snippet we see:
(node:1) AutopaginateTrueWarning: Providing a pageSize without setting autoPaginate to false will still return all results. See https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#auto-pagination for more information on how to configure manual paging

Thanks!
