Add a command to run totp integration tests as part of the CI

[prameshj]

These tests will run against the real backend, since we do not have emulator support yet.

Running yarn test:browser:integration:prodbackend passed against my own project.

Run against the jscore-sandbox-141b51 passed as well - https://github.com/firebase/firebase-js-sdk/actions/runs/4075626218/jobs/7219953819
