🐛 [cloud_firestore] `experimentalForceLongPolling` option

[jbaptisteroesch]

Users on certain corporate networks are experiencing the issue, Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds likely due to proxies, ad blockers, etc. This issue is known and the team is currently addressing it in the Firebase JS SDK. See: https://github.com/firebase/firebase-js-sdk/issues/1674.

However, it appears no similar action has been taken on the Flutter SDK. An issue was raised a few months ago, but was quickly closed without a definitive resolution. See: https://github.com/firebase/flutterfire/issues/10534.

The options experimentalForceLongPolling or experimentalAutoDetectLongPolling do not appear to be available in the cloud_firestore plugin (v4.8.1). Did I overlook something, is it a planned feature, or does it not exist at all? Is there a workaround if these settings are unavailable?

The issue is difficult to reproduce and highly situational. I was previously unaware of the problem and am finding it challenging to consider moving the project to another backend service.

Thank you in advance for any assistance.
