bigquery/storage/managedwriter: TestIntegration_ManagedWriter failed

Note: #4968 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (79c47a7), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

Unclear what happened here. Closing and seeing if it recurs.

[flaky-bot]

Oops! Looks like this issue is still flaky. It failed again. 😬

I reopened the issue, but a human will need to close it again.
