samples for external-account: should acquire ADC for file-sourced creds failed

[flaky-bot]

Note: #1757 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

commit: 16e5cae
buildURL: Build Status, Sponge
status: failed

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 (16e5cae), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).
